Ask Alo shoppers on Reddit whether the brand runs small and you’ll get all three answers: size down, size up and true to size. They can all be right, because Alo cuts its leggings to squeeze and its Accolade sweats to hang loose. So does Alo run small? Overall, no. Most Alo runs true to size: the leggings and bras feel small because they compress, and the Accolade and Muse sweats run big on purpose.
One shopper almost swapped a pair of small leggings for a medium because they looked tiny out of the bag, then found they fit. At $78 to $148 a piece, that’s a return worth skipping. At Nimble Journal, every verdict below comes from the Fit line Alo prints on each product page, plus what owners say after wearing them.
Quick answer: No, Alo doesn’t run small overall. Alo lists its Airlift and Airbrush leggings as true to size, but their compression makes them feel snug. Accolade hoodies, sweatshirts and Muse sweatpants run big, and Alo suggests sizing down for a closer fit. For Airlift bras, size up for a fuller cup.

Does Alo Run Small or True to Size?
Alo runs true to size in most styles, going by the Fit line on its product pages. The confusion comes from compression. Airlift and Airbrush fabric hugs hard, so the right size can feel one size too small the first time you pull it on.
Snug and small feel different once you know what to check:
- Snug (right size): the pressure feels even, the waistband stays put through a squat, and the fabric looks smooth and opaque.
- Small (wrong size): the waistband digs or rolls, the fabric looks thin or shiny where it stretches, and you feel it pulling at the seams.
One Reddit shopper put it plainly: a small that “fits but a wee bit snug” means the fabric “has to stretch too much,” and they expected it to wear out faster.
Alo’s stretch also covers more bodies than the letter suggests. In its post What to Know About Our L & XL Sizes, Alo says its 4-way stretch fabrics mean its large fits up to a size 14, “two sizes beyond most activewear brands’ size large,” and its XL fits up to an 18. That post dates from 2018, and the current chart now runs past XL.
Answers online clash because they mix product lines. A UK retailer’s legging guide tells shoppers to size down in most Alo leggings. One PureWow writer found the Airlift ran small. Alo calls both true to size, and the Accolade threads saying “size down” are about sweats.
Do Alo Leggings Run Small?
No. Alo lists its Airlift, Airbrush and Goddess leggings as true to size. They feel smaller than a cotton legging because each is made with compression, and Airlift squeezes the hardest. That squeeze is why so many shoppers ask “does Alo run small?” about leggings first.
Airlift Leggings
Airlift is Alo’s high-compression fabric, an 82% polyester and 18% elastane blend with a subtle sheen. Expect a hold-you-in feel from the first wear. Owners on Reddit say Airlift feels tight at first and relaxes a little after a few wears.
Reviews on Alo’s own High-Waist Airlift Legging page disagree. One owner wrote “Size up!” while another wrote “Fits true to size” and said they never had to pull them up during a 45-minute class. As general advice, stay with your usual size and size up only if you sit between two sizes or want less squeeze. A few Reddit shoppers size up to avoid a flattened look at the back.
Airbrush and Goddess Leggings
Airbrush is medium compression with a matte finish, so it smooths without the vise-grip feel. Alo lists the High-Waist Airbrush Legging as true to size, with an 87% nylon and 13% elastane blend. One shopper in a Reddit thread on Airbrush leggings said they wear a medium in most gym brands and a small in Alo.
The Goddess Legging uses Airbrush fabric with ribbed lower legs, and it’s built extra long. Its inseam runs 32.5 to 33.5 inches by size, so it bunches at the ankle or pulls under the heel by design.
Picking the Right Length
Length depends on your height. On Alo’s size chart, full-length leggings have a 28 to 29 inch inseam, 7/8 runs 24 to 25 inches, and capri runs 21 to 21.5 inches. Alo describes the 7/8 as “perfect for petite girls or for taller girls who want to show a little ankle.” Measure your own inseam from groin to floor with no shoes on, then pick the length that lands where you like it.
Do Alo Hoodies, Quarter Zips and Sweatpants Run Big?
Yes. Alo cuts its Accolade and Muse loungewear boxy or roomy on purpose, and its own Fit notes tell you to size down if you want a closer fit.
The Accolade hoodie, crew and quarter zip are all unisex and cut for a boxy, oversized look. Alo says to size down once on the crew and quarter zip. The Accolade sweatpants go further: Alo says to size down “once or twice.” The straight-leg version also has a longer inseam, from 30.5 inches in XXS to 31.5 inches in M and up.
Owners back this up. One Reddit shopper who is 5’6″ wears a small in the Accolade crew for an oversized look. Another said Alo crewnecks in a small are “still baggy” on them. On the quarter zip, a commenter described “a much roomier baggy fit since they are unisex.” Our Alo Accolade hoodie review covers that hoodie’s fit in more detail.
The Muse Sweatpant is roomy too, and Alo suggests sizing down for a closer fit. The matching Muse Hoodie breaks the pattern: Alo lists it as “True to size,” “designed for a cropped fit.” Keep your usual size in that one.
How Do Alo Sports Bras and Tops Fit?
Snug. Alo’s Airlift bras are high compression, and the Airlift Intrigue Bra note tells fuller-cup shoppers to size up.
The Airlift Rebel Bra and Airlift Devoted Tank are listed as “True to size” with high compression. Tops are easier. The Cropped Timeless Tee is “True to size,” “designed for a slightly fitted look with a cropped silhouette,” and the Aspire Tank is “True to size,” “designed for a body-skimming, cropped fit.” Take your usual size in both.
Alo’s bra guide matches your band and cup to a letter size:
| Band | A | B | C | D |
|---|---|---|---|---|
| 30 | XS | XS | S | S |
| 32 | XS/S | XS/S | S/M | S/M |
| 34 | S/M | S/M | M/L | M/L |
| 36 | M | M/L | L | L |
| 38 | L | L/XL | XL | XL |
| 40 | XL | XL/2XL | XL/2XL | XL/2XL |
Fit also depends on your ribcage, as one Reddit commenter pointed out. If you land on a split size like M/L, take the larger one for a fuller cup.
Does Alo Run Small for Men?
No. Alo lists its men’s Conquer line as true to size, and most of it is cut relaxed.
The Conquer Reform Crewneck tees and Conquer Muscle Tank are “True to size,” “designed for a relaxed fit.” The Conquer Max Performance Jogger is true to size with a slim, tapered leg. The 7″ Conquer React Performance Short is true to size, though Alo notes a shorter inseam than its classic 7″ styles.
Men’s sizes run S to 2XL. On Alo’s men’s chart, a medium fits a 38 to 41 inch chest and a 32 to 34 inch waist.
Accolade is the one to watch. The same Accolade pieces appear in the men’s and women’s sections, sized XXS to 2XL, and a Reddit commenter confirmed it’s “the same product with the same sizing.” So the oversized cut and the size-down advice apply to everyone.
What Size Should You Get in Alo?
Start from your usual US size and find its Alo letter in the chart below. Then adjust only for loungewear.
| Alo size | US size | Waist (in) | Hip (in) |
|---|---|---|---|
| XXS | 00-0 | 23.5-24.5 | 33-34 |
| XS | 2-4 | 25-26.5 | 34.5-36 |
| S | 4-6 | 27-28.5 | 36.5-38 |
| M | 8-10 | 29-30.5 | 38.5-40 |
| L | 12-14 | 31-33.5 | 40.5-42.5 |
| XL | 16-18 | 34-36.5 | 43-45.5 |
| 2XL | 20-22 | 37-40 | 46-49 |
A US 4 sits in both XS and S, so let your waist and hip measurements break the tie. Alo says to measure your waist at belly-button level and your hips at the fullest part.
Then follow these rules:
- Leggings and bras: take your usual size. Between sizes, the smaller one gives more squeeze and the larger one gives less.
- Fuller cup in the Intrigue Bra: go one size up.
- Accolade, Muse Sweatpant and Suit Up Trouser: size down for a closer fit, and up to two sizes on Accolade sweatpants.
- Skirts: the Airbrush High-Waist Good Form Tennis Skirt is “designed for a more body-hugging fit,” and Alo suggests sizing up for a relaxed one. The Momentum Skirt and Accolade Skirt are true to size.
- Check the size menu: not every style comes in 2XL. Many leggings stop at L or XL depending on the color.
Returns take the sting out of a wrong guess. Alo’s returns page says returns are free and accepted within 30 days, as long as tags are attached and the piece is unused. Final Sale items can’t be returned. If you’re torn, order both sizes, try them on with tags still on, and send one back.
Does Alo Run Small Compared With Lululemon?
Alo leggings can feel smaller because Airlift and Airbrush are made with high and medium compression. Shoppers don’t agree on which brand runs smaller overall.
In one Reddit discussion, a commenter said they’re “usually a 2 or 4 in lulu,” but need an XXS in Alo. Another shopper wears a medium in most gym brands and a small in Alo. Both found Alo roomier, which goes against the idea that Alo runs small.
The safer move is to skip brand-to-brand guessing. Alo maps each letter size to a US size range, so convert from your US size and measurements, then read the Fit line on the exact style.

Final Thoughts
So, does Alo run small? Here’s the short version, style by style:

Frequently Asked Questions (FAQs)
Q. Should I size up or down on Alo?
It depends on the piece. Take your usual size in Alo leggings and bras, and size up in Airlift bras if you have a fuller cup. Size down in Accolade and Muse loungewear for a closer fit. Alo’s Fit notes on each product page say exactly this.
Q. What size is an Alo medium?
An Alo medium is a US 8 to 10. On Alo’s size chart, that’s a 29 to 30.5 inch waist and a 38.5 to 40 inch hip. Measure yourself before ordering, because leggings with high compression feel tighter than the number suggests.
Q. What size is XS in Alo?
XS in Alo is a US 2 to 4, with a 25 to 26.5 inch waist. XXS covers US 00 to 0. If you’re a US 4, compare your hip measurement with the chart, since that size sits between XS and S.
Q. Why is Alo sizing so big?
The big fit mostly comes from loungewear. Alo cuts the unisex Accolade line for “a boxy, oversized look” and the Muse Sweatpant for “a roomy, relaxed look.” Alo’s leggings run true to size, so the oversized feel belongs to the sweats.
Q. Do Alo Airlift leggings run small?
No. Alo lists Airlift leggings as true to size, made with high compression for a snug fit, so they feel tight. A PureWow reviewer found them small, and Alo page reviewers are split. Size up only if you sit between two sizes.
Q. Does Alo run small like Lululemon?
Shoppers disagree, and some Reddit commenters find Alo roomier than Lululemon. Alo’s leggings feel compressive, which can read as small. Go by Alo’s US size chart, and see our Alo Yoga vs Lululemon comparison for the bigger differences.
Q. Does Alo shrink after washing?
Alo’s care guide, updated November 3, 2026, warns that dryer heat leaves fabrics stretched out and fitting worse. It says to wash cold and air dry activewear, the same routine our guide on how to wash Alo yoga clothes follows. Airlift and Airbrush product pages allow tumble dry low, but air drying is Alo’s safer pick.
Q. Does Alo go up to XL?
Yes. Alo’s size chart runs up to XL (US 16 to 18) and 2XL (US 20 to 22). Accolade pieces come in 2XL. Many leggings stop at L or XL depending on the color, so check the size menu on each product page.
