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.
