Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.

Perfect Suit!
Size: 10, Color: Navy Blue-bowtie, Size: 10, Color: Navy Blue-bowtie
So cute! This slim suit fit my 9 yo son great! He’s 4’7 and 73lbs. He wore it to perform in his school’s talent show and again at Easter. We got tons of compliments both times! It’s a good quality, not cheap materials, and he said it was comfortable (he wore it for hours each time). Love, love, love this cute suit!
