Nice Brown
The suit looked very nice. The fabric is good quality if it’s great for the size that is supposed to be I would say the only thing that gives me a little concerned with the pants are a little short but other than that, it’s wonderful. It looks amazing.

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.
