Stylish and great value!
Color: Medium Grey, Size: 14
This grey suit was a great find for a school ceremony and will definitely be used again. The neutral color makes it easy to pair with different shirts and ties, and it has a modern, clean-cut look. The jacket and pants fit nicely after a quick press, and the quality was better than I expected for the price. It lost a star only because the waist on the pants needed a slight adjustment, but overall, we’re very happy with it!

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.

Super soft, runs small, long tail
High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.

This shirt is a cheat code
Color: Black, White, Navy Blue, Light Gray, Size: XX-Large
These shirt fits my body so perfectly! I’m 6’5” 310 pounds but I look 260 pounds. I sweat easily and I’m very sensitive to the material a piece of clothing is made of. This shirt is lightweight, extremely breathable, and feels like silk on the skin. It compliments and accentuates my contours to enhance my physique. I only tried on one and I’ve already ordered 12 more hehe. This is a cheat code.

I Love the collar
Color: Black, White, Navy Blue, Wine Red, Size: Large
Great T-shirt. I can wear this casually with jeans or with a sports coat. The fabric is soft. There is no label in the collar, so you can wear it however you want.
