Good quality with an even better price for all the items you get
Color: Black, Size: 8 Years, Color: Black, Size: 8 Years
A little large/long but good quality. I think my son is pretty average sized for an 8 year old. My fault for getting it last minute so we didn’t have time to get it fitted. The quality was better than expected especially for the price. He told me he was super comfortable in it so that was the biggest win! Shirt not included and he took his jacket off for the picture.

Colour and Sizing are good
Color: Dark Green, Size: 6 Years, Color: Dark Green, Size: 6 Years
Very nice material. Sizes are accurate. I love it. I bought size 6 for my 7 year old son ( he's a little on the smaller size) and Size 12 for my 10 year old ( he's tallish and skinny) because I want them to last a few years.

Good Suit for 8th grade formal
Color: Black, Size: 16 Years
Great suit fit true to size. Come with suspenders and tie although the tie is one size so I think it’s the same size regardless of the suit size. Quality material held up to ironing and the washing machine.
