Based on 6 reviews

Very cute and soft. The straps slip on me a lot but still worth the strap struggle

Magdalene Beckman
So comfy

Saw this top on IG and decided to try it out. I have to say it fits really well with the adjustable straps and is super comfy!

Fits: True to size
The thick straps

This crop is great! Love the thick straps and open back. I have bigger traps so adjustable straps are really nice. I am constantly having issue with the neckline pulling up on my sports bras while lifting and so far this one has been perfect.

Good fit for DD

I am size DD and have trouble finding tops bras that are supportive and fit well but are actually cute. This has adjustable straps which really helps. I prefer thin straps over the thick ones though.

Love the adjustable straps

I have a large shoulders and lats but a small waist. Its hard to find tops that don't cut into my shoulders or pull away around my waist. This top has really comfortable straps.
