good fit for cheap!
Special Size: Short Sleeve, Size: Small, Color: White
I like the material it’s more athletic, not see through, cuts off at a flattering length, good stretch my only point deduction is that I wish it took in a bit more in the waist to fit a bit better I wear a 32D bra with a 25-26in waist

Cute but beware of the length
Special Size: Long Sleeve, Size: X-Large, Color: Bright Red, Special Size: Long Sleeve, Size: X-Large, Color: Bright Red
It’s cute but the fit is off. If you’re short like me (5’4) then the leggings and sleeves are long but overall it’s cute. I just don’t wear it often because of the fit.

So soft!
Special Size: Short Sleeve, Size: X-Large, Color: Navy
Bought this for the gym and I love it! It’s so soft and breathe able. I don’t get too hot and it’s the perfect length. I’ve bought it in 2 colors!

Great fabric!
Special Size: Long Sleeve, Size: Medium, Color: Navy
Great quality! Perfect for athleisure wear or a workout at the gym. It is a bit shorter than I thought, but still fine for every day wear.
