My favorite pair
Special Size: 7" Inseam with Pockets, Size: Large, Color: Black
The most comfortable pair of shorts I own. Material is soft, pockets are the perfect size.

Cute but run big
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Flamingo Pink
Color is fantastic. Very naked feeling. Runs big. I’m a size 12/14 and usually wear XL with them sometimes feeling tight. I am pear shaped - 35” waist, 47” hip and these fit but were quite loose in the waist. I might consider sizing down if I wanted to tighter. They would be very a bump-friendly non-maternity option

Super soft with great support
Size: Small, Color: Light Blue/White, Size: Small, Color: Light Blue/White
Bought the top and the matching leggings for a bachelorette trip. Absolutely love them. It’s so soft, it didn’t bother my incredibly sun burned chest at all, the baby blue with white contrast binding looks exactly like the listing.
I am a 32C and got a size Small, so it fits perfectly and provided great support. This is 100% a bang for your buck and I will likely buy it again in the other colors.

FLATTERING, HIGH QUALITY
Size: Small, Color: Slate Grey/White
Quality item!! I would compare these to CRZ YOGA. They do not stretch, not see through, and feel buttery soft. I have only used them working out in a reformer pilates class in which I did not notice the leggings falling or the bra stretching. I would size down on the bra. I am a postpartum mommy and purchased a medium and I am nursing. It still was a little too big for my liking. So I went with a small on this order and it fit perfectly. The white lining on the bra and leggings I feel bring a flattering look to my waist for those ladies looking that that aspect. They pulled in all the right parts without creating any spill over. It might not be useful for a high impact workout like running or spinning but any weight lifting or Pilates-type classes it would be perfect for! I bought another set I love them so much. I ran them in the washer and hung dry them as I do all my fitness clothing items.

Pretty Good!
Size: Medium, Color: Flamingo Pink/White
Very comfortable while providing support. Excellent price point. The only thing dropping this to 4 stars is that the straps seem a bit long/loose at the top.
Despite this, it still provided great support for my HIT class.
