Nice suit great value
Size: Medium, Color: Light Blue, Size: Medium, Color: Light Blue
Got this suit for my son to wear to a wedding. It arrived a day or two then the except it delivery. I was concerned if it would fit because of the size chart. He is tall and skinny so I got the medium. When he tried it on it fit him perfectly except the waist was a tad too big but with a belt everything worked. I took it to the cleaned to have them press it. Great value, nice quality material, light weight and comfortable for spring/summer events. The wedding was outdoors. He looked very handsome unit. Was very pleased.

Not Seersucker, more a Blue pinstriped suit.
Size: XX-Large, Color: Blue
This is not Seersucker!!
Granted the suit will be cool in summer and looks good, but material is a blend.
The pants are very large, while the top fits perfectly.
I’d go with a regular cut, not slim for better fit. But for the price, no complaints.

Great Suit for Hard to Fit Guys
Size: X-Large, Color: Light Grey, Size: X-Large, Color: Light Grey
This fit my husband perfectly. The elastic in the waistband is great, he was very comfortable all day. The only complaint is that the material is a little thin.
