The quality of the top is wonderful, the print is gorgeous and vibrant, the material is nice and breathable; however I found that this top ran big. I really could have used an XS, but was on the edge of the small measurements and figured since it was a sports bra I could get away with it. I was planning on wearing this for a MNSSHP night, and I can probably make it work for that, but I definitely couldn’t run in it. While I did find it to be large all over for me I was expecting it to be more form fitting and body hugging as a long line cropped sports bra. The portion of the bra below the bust line was probably about and inch and a half too large/wide on me all the way around. For reference I am 5’1, 112lbs, 32B bra size, and typically a size 0 in pants.

The skort is beautiful and very vibrant, fits according to the size chart, comfortable, nice material, pockets in the shorts, and the seller was absolutely wonderful to work with and extremely responsive to questions.

The tank I got which was the crop top with no bra doesn't match any of the pictures. The tank is a square neck- which none of the product images are so it was a bit misleading and a tad disappointing since this shop doesn't accept returns. It would have been more helpful to have actual photos of each top or bottom and have it stated in the images which was which because there are so many options it's hard to know which is the one you're ordering. But material is very thin, similar to a child's costume.

Response from Tamara

Thank you so much for your feedback! I've recently switched the crop top that I've been using and it's true to the image on the size chart but I need to update my images! so sorry!
