Runs big, and fabric may not be same color as picture
Color: Medium Grey, Size: 16, Color: Medium Grey, Size: 16
This suit was a good find for us, as we usually dress up for church, and my 13 yo son often wears suits. He normally wears a size 16, so that’s what we ordered, and in dark charcoal gray. The suit we got was a light, heathered gray that didn’t look much like the one in the picture. It was very wrinkly and thin, and a little scratchy. Also, the sleeves were way too long and the torso cut of the jacket was pretty wide. The pants were very large in the waist, but fit him decently in the length (he’s 5’4” and weighs 90 lbs). Overall the suit looked like it was drowning him, so I would order a size down unless you have a larger child/teen. Because of the ill fit, I haven’t had the chance to see what the suit looks like on him as it’s supposed to, but I guess I’ll return it or wait a year or two until he fills it out a bit more. Not overly impressed with the quality, so I’m not sure I’d pay $55 for this one again.

Slim and Sleek
Size: Small, Color: Black, Size: Small, Color: Black
This slim fit suit was awesome and great. My son loved it and it went perfectly well with my daughter's dress. The perfect way to twin. If anything my son is 5'3 120 lbs and the pants and coat fit a bit long and just took it to a seamstress to get it better fitted for him. Other than that for the price, value, comfort, and look I highly recommend this and so does my son.

Suited me Well
Size: Small, Color: Black
This 2 Piece Slim Fit Suit Set is hands down the best suit for the price. I bought it for a formal Christmas work party, and it was such a cheap, easy, and quick way to get exactly what I needed — especially since I hate shopping. Honestly, you would never guess I paid as little as I did. It looks sharp, fits great, and feels much more expensive than it is. The color was a true black, which I really appreciated. It looked clean and classic — perfect for a formal event. It did arrive a bit wrinkled from the packaging, so I had to iron it initially. But it was very easy to iron, and once I did, it stayed pretty crisp throughout the night. It didn’t wrinkle much at all while wearing it. It’s also way better than going to a store and paying triple the price. And definitely better than renting — now I actually own it and can wear it again whenever I need it. The fit is perfect if you’re slim. I’m skinny as a rail, and the slim fit worked exactly how I hoped. The jacket isn’t too tight, not too long, and I can move my arms easily without feeling restricted. The whole suit is comfortable and easy to move around in — not stiff like some formalwear can be. It also has handy pockets for your phone and wallet. Overall, you can’t go wrong with this suit. Great price, true black color, comfortable fit, and sharp look. Highly recommend.

Amazing fit and quality for the price
Size: Medium, Color: Red
Gotta say I was 100% impressed w this suit! And for the price!!?? Nice fabric. Great fit. Great quality. Fit right out of the box! No alterations were even needed. My 14 year old son is 6'2 and around 155lbs. Broad shoulders. Slender build. We ordered the medium and it fit just right. You really cant go wrong w this suit even if you need to get some alterations you cannot beat the price.

Quick Delivery & Surprisingly Good Quality
Size: Large, Color: Light Gray, Size: Large, Color: Light Gray
I needed a suit on short notice and didn’t want to spend a fortune, so I took a chance on this gray suit—and I’m really glad I did. For the price, I wasn’t expecting much, but the quality is honestly impressive. The fabric feels solid and looks sharp, not cheap or shiny like other budget suits I’ve seen. Shipping was fast—I received it in just a couple of days, which was perfect for my tight timeline. The fit was nearly spot-on right out of the box. The jacket and pants fit well overall, though the sleeves were a bit long for my arms. If you need a reliable suit fast without spending a lot, this is a solid option. It exceeded my expectations for the cost and turnaround time.
