Well made and comfortable
Size: Small, Color: Slate Grey/White, Size: Small, Color: Slate Grey/White
Very cute and comfortable workout set! I bought the leggings and the matching sports bra sold separately. I am 5'4" , 125 lbs and bought a small in each. The leggings are tight but not too tight, doesn't dig in and doesn't roll down. Well made and thick material. Worked great for a very sweaty hot yoga class. I'll be buying more in different colors.

Fall or Winter
Size: Large, Color: Black/White
For me, these leggings are a perfect fit and perfect for Fall & Winter, maybe early Spring. Summer though, I would not dare. Comfort wise, the leggings are soft and perfect for the gym, grocery shopping, lounging, even sleep. I passed out in mine and slept just fine.

Beautiful and slimming leggings
Size: Large, Color: Slate Grey/White
Very soft & comfy hip slimming with the white piping! Best part — I bought the matching top in a different size, now I have a perfectly sized set for me 😊

BUTTERY SOFT, HIGH QUALITY FEEL
Size: Medium, 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 it fits perfectly. Once I get my core back in shape I can probably size down to the small. 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.
