Total disappointment
Color: White, Size: X-Large, Color: White, Size: X-Large
Coofandy is my go to shop. Has been for years! Need this blazer for an event tomorrow, and it came in today with a yellow stain from inside the package. Can't return it because I need it, so it's going straight to the cleaners. Fits perfect as normal. This is my first, under 5 star review for Coofandy.

Its description was enhanced in a favorable manner.
Color: Black, Size: Medium
When I made the purchase, the product description clearly stated it was for regular-sized individuals, not for slim people, with measurements suited for a regular body type. My measurements fall exactly between medium and large. Medium fits me just a little snug, while large is too big—my perfect size is right between M and L. Now, the description has been updated to specify it’s for slim individuals, which is a more accurate description. The previous description was incorrect, which is why I am returning the product. However, the product itself is good.ente.

Perfect suit for dapper groom
The seller was easy to work with and got the suit to us in plenty of time before the wedding. I took my fiancés measurements and picked the suit size according to the chart, and it fit him perfectly. He looked so handsome for our day in a suit that we could afford. Excellent quality considering how little we paid for it!
