This is a terrific purchase.
Size: Large, Color: Navy Blue, Size: Large, Color: Navy Blue
Amazing for the price. It’s a wonderful suit fit just right for a 5’10”. 145 pound male.
The quality is surprisingly wonderful for this suit and the color is accurate. As in the picture it is a slim fit and accentuates his figure. I would highly recommend this for a purchase. (be sure to use the measurements on their description before ordering). After a steam and a press we were ready to go. The packaging was very nicely done also.

Perfect fit.
Size: Large, Color: Dark Gray
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.
