I’m 5’9”, about 180 lbs. I got an L based on the Amazon recommendation. The size chart showed the pants being a 36” which is big for me but it’s those that stretch so if you’re a 34” like me, it’ll fit perfectly. No alterations needed for me. Great fit, good looking suit, nice material. I immediately bought another and hope it fits as good as this one. Genuinely impressed.

Great quality, better than a rental.

Size: 4X-Large, Color: Navy Blue, Size: 4X-Large, Color: Navy Blue

This suit was a pleasant surprise in quality! Just note, sizing isn’t perfect since it’s a set, so the pants were really long and the waist slightly bigger than my husband’s actual size, as we had to fit for his chest and shoulders. However, we were able to hem the pants quite easily and he just wore a belt which worked perfectly. For the price and quality you receive, well worth it. We ended up using a different tie than given so it would match my dress. Worth every cent even if worn once since rentals are way more expense. This held up for a full 8hrs of schmoozing and dancing and is still in great shape.
