great suit for a great price
Size: 38, Color: Hot Pink
I was shocked at the quality of the material, the suit and pants feel very nice and stretchy, however the tie is a little cheap and dosent match the same color. for the price its an impressive quality. it ran a little big but i was able to return and get a smaller size in a timely manner so no big deal.

Looks good and seems to be quality product.
Size: 34, Color: Apple Green(with Tie Set)
The quality is great for the price but the size is a little off. 34 is too big and 32, the pants is little tight.

Good, but the reviews messed me up.
Size: 40, Color: Hot Pink
I like this suit. I really do. It's much better quality than I expected. Color matches what I saw on my screen. 100% worth the $70. My problem was listening to reviews. Most say fit perfect, follow their size chart. Another says their son is normally size 32 and she ordered a 38 and it fit perfect, so make sure to order 1 or 2 sizes up. My advice is go with your gut. My son is normally a size 34...I ordered a a 36 because of both their size chart and reviews. After looking at the size chart I told myself that's too big, but said no, reviews state this is perfect and it is 1 size up from what he wears. As I was ordering I was telling myself "this is going to be too big, I just know it." Guess what? I was right...and now I'm paying for these size 4XL pants to be tailored (am I stupid or is a 36 supposed to be 4xl?? I still wonder if this is my mess up). The jacket actually fit quite nicely, maybe a tad too big, but not enough to even need to tailor it. Honestly this company needs to let us pick a size for the jacket and a size for the pants, instead of it being almost a guarantee one of them will be too big.

Zero stars

I was sent this package with the item dirty. Black stains throughout as if it was worn right before selling it, which IT WAS. I found someone’s ID in the pocket and chewing gum wrapper. Never again.

Loved it.. Slim fit Prom suit!
Size: 30, Color: White
I absolutely loved this suit!! It fit my son PERFECTLY!! It’s a true slim fit like the kids like these days. I’ve bought several suits online and none of them fit like this one. They SAY slim fit but they’re not. This one was!! 👌🏽
My son is small. He’s a Junior this year and wears a size 30… it’s true to size! ❤️ He’s about 5’8” 125lbs and still had some room in the length. He would of got the length hemmed a bit cuz he likes his pants right above his ankle. If your son is taller, you might not have to hem. We ordered the white.
Unfortunately I had to return it because his girlfriend switched color schemes from pink & white to pink & black so he wore a blk suit he already had. I was tempted to still keep it because that’s how much I liked it on him. He liked it too 😩 But chances are he wouldn’t be able to fit it next year so I decided to return it.
But, I’m definitely buying this suit again next year… hopefully the other colors fit like the white one, just incase his girlfriend wants a different color.
The white was not see through. Very good quality especially for the price. I felt bad returning it… but trust me, I’ll definitely buy it again next year for homecoming/prom!!
