Sizing is way wayyy off.
Size: 5T, Color: Beige
I ordered three of these in different sizes for my 5yro&7yro -They’re average to their age sized kids. So ordered size 5 for my 7 yro (I read other reviews on it being big). Everything fit except the pants we’re closer to a size 8 (I ordered a size 5 remember) so disappointed. And a size 4 for my 5yro. The size 4 pants fit my 7yro! But not my 5yro at all. The rest of size 4 outfit was only a little big but not big enough to trade up to the other child. Unfortunately the gigantic pants are beyond the problem. They are definitely running 3 sizes too big. They’re not even something I could fix with my sewing machine. Company says they’ll work with you & send one item “free”but then say their shipping & handling fees are more expensive than the suit. Feels like it’s a ploy. update, the third suit arrived after a month of waiting and its a size 3-well its supposed to be a size 3. The pants are the size of an 8 year old. Im pissed. it's now past the return date, I have 3 suits for $45 each, and I had to rig the pants to fit my 4yro for my wedding. looked like crap obviously bc an 8yro's pants don't fit a 4 yro.. Don't bother buying from this company unless you're buying for an absurdly proportioned person.

Very high quality suit for the price! Might as well buy, then rent.
Color: Deep Grey (Stretch Fabric), Size: X-Small
I bought this for my son for his Prom, as he decided to go last minute. He weighs around 125 pounds and is about 5'11. The XS fit was pretty amazing. As the supplier says, follow the size chart on the second picture. There is also some stretch to the material and the pants have belt loops. The only thing we noticed that we didn't like is that the sleeves were a little large at the opening around the wrist. Since the cuff-links are sew on, there isn't really on easy way to adjust this. All in all, this was a great purchase and I would highly recommend YND suits.

Good buy for sure.
Color: Burgundy (Stretch Fabric), Size: X-Large
The suit looks and feels great for the price I’m 6’3 190-200lb and ordered a size XL. I’m going to have the sleeve dropped a tad bit and waist taken in. The hem is perfect and to my liking. Will be buying 2-3 in the future.
