Good quality but sizing is not accurate
Color: Black, Size: Medium
The vest looks really nice and the fabric feels like good quality, so no complaints there. However, the sizing was not accurate based on the measurements provided. I ordered according to the size chart, but it didn’t fit as expected, so I had to return it. If you’re planning to buy it, I would recommend double checking or maybe sizing up to be safe. Overall, the product itself seems well made, but the sizing issue was disappointing.

Suit jacket
This suite jacket was a perfect fit for my husband. It went well with the vest and tie we also ordered. The material is a good quality it held up all day and night. It's not to heavy to make it uncomfortable. It is perfect for our date nights and special occasions.
