Nice suit for the price!
Color: Light Grey, Size: 12, Color: Light Grey, Size: 12
This really is a very nice boys suit, especially for the price they are asking. My kids don't wear suits too often, maybe once or twice a year for special occasions so I don't need really expensive suits for them. The material is actually really nice on this. The color looks great and the pieces are sewn nicely. The adjustable waist band is really nice on the pants because my kids are on the slimmer side and this helps with fitting. You can also wear a belt with these if needed. I washed on delicate cycle and dried on delicate cycle a little, then finished by air drying. They washed and dried very nicely with minimal wrinkling. The front pockets are real and useable on these, which isn't always the case with boys suits. Overall would 100% recommend

Nice looking suit that runs big
Color: Light Grey, Size: 6, Color: Light Grey, Size: 6
This is a beautiful light, gray linen suit size 6. It looks high end and it is a baggy fit, not slim. This suit is double breasted with a satin lining inside. There are two pockets in the jacket and one small smaller pocket for a handkerchief on the jacket. I did order a size 6 but this fits way too big for a size 6 I’m thinking it was more like a seven or an eight. The pants have a zipper, which moves very easily and 2 pockets. The Pants have belt loops. Both the the pants and jacket are longer than normal. My son is tall, so I was really surprised that these are so baggy and so long. I would definitely double check the size. there’s no size chart online so maybe I would go one size down. It does look like a quality made suit. The sizing is just off.

Bought this for my son to attend a wedding on the beach. It looks very good, the color is beautiful and is true to size. He is 14 so I got size 14. He is 5’7” and weighs about 110 lbs. the pants length was perfect too. Just needs a little ironing.
