Great Fit and Price While Updating My Wardrobe
Color: Shortbread, Size: Large
As I’ve been getting fitter, my old clothes started looking too baggy, so I needed something that fit better without breaking the bank. This COOFANDY chambray shirt turned out to be exactly what I was looking for—lightweight, wrinkle-resistant, and stylish enough for casual or dressy wear. The fabric feels soft and breathable, and it pairs easily with jeans or slacks. Since I’m still losing weight, I didn’t want to overspend on clothes I may size out of soon, and these hit the sweet spot for both quality and affordability.

Great suit, great price
Size: Small, Color: Dark Grey
Had to send back because jacket (small size) was too tight around my upper torso so you could tell it didn't fit right. The pants though were the perfect fit, so much so I contemplated keeping the suit - it looked expensive. The suit was delivered as promised so I am thankful for that. Beause I needed it for a wedding the next day I couldn't wait on this seller as I didn't see them offering an overnight delivery. But kuddos to them though for working with me
