Stylish
Size: Large, Color: Black, Size: Large, Color: Black
Fits like we had hoped. We purchased another one different brand and it was terrible quality. But this jacket was my son’s style and comfortable. Just what he was looking for

Shiny Small Sequin Blazer
Size: Small, Color: Black
This tuxedo blazer is one for the looks. It’s shiny black 100% polyester material, with a mesh net on the left side that has dark gold plastic sequins sewn on in a tree pattern. The material is taut with seams at the sides and the middle of the back. There is a single button. There are no pockets outside nor inside the jacket. The quality will hold up and is a decent value for the money.
This was for a 5’5 male of slim build and fit quite snug. The measurement in inches: 17 - shoulders; 23 - sleeves; 27-1/2 nape to bottom of blazer.

Size a tad small
Size: Large, Color: Black
So many compliments so don’t buy this if you don’t like people to notice. I’d say fits a tad on the small side.
