★★★★☆ — Angelina, Oct 2025

I love their shirts. They are very reasonably priced, and the material is a nice weight and fit.

★★★★★ — Able, Jul 2021

Happened upon this store in O'Fallon, Illinois after having my nails done. I just thought that I would browse to see what I could see. Well, let me tell you that it was the best thing I could have ever done. It caters to ladies sizes 2-12 and 14-24 plus size and the quality is amazing for the price.
