3 piece suit at a great price
Size: Small, Color: Black
My son needed a suit, and these worked out great. It looks nice. Don't just assume the size, go by their size chart. I was going to order him a medium, by the chart recommended a small, and it fit perfect. The material doesn't look like an expensive suit but it worked out great for him.

10/10 Great suit , great price
Size: X-Small, Color: Red, Size: X-Small, Color: Red
Absolutely stunning for the price. Very flexible and good fit. I wish the XS was just a bit smaller but it's good. Middle of the ground with thickness it's not a cheap thing costume feel but it's not your typical heavy suit. Which I much prefer. It's lightweight but not cheap. For the price you can't ask for a better suit. I was thinking it was more of a one time use, but it's a very good long term suit. Feels very well and allows great mobility. I featherweight conceal carry and it's very easy to hide my pistol in the suit because of its flexibility. 10/10 would definitely recommend

Good Suit
Size: X-Small, Color: Black
This suit is pretty nice. The fabric isn't extremely thin and cheap-feeling, and it fits really well. The shipping was really fast too. My son is 5'9" and weighs about 150 lbs. We ordered a medium first, but it was too big, so we returned it and ordered an extra small. The extra small fits perfectly.

It's a fun/unusual color, but not "celery"
Size: Medium, Color: Celery Green, Size: Medium, Color: Celery Green
Can't comment on the fit because we didn't take it out of the bag. I gave it 4 stars because 𝙦𝙪𝙖𝙡𝙞𝙩𝙮 of the suit looks really nice through the plackaging, but we didn't open it up and try it on because the color could not be further from what we were expecting. It's actually a really cool and unusual fun fabric, but not really describable as any shade of green which is what I was going for. It's more of a beige tweed whose tiny plaid upon careful examination even has slightly blue threads.. or is that lavender? In fairness to the manufacturer, I tried and tried to get a photo with lighting that accurately represents this fun and unusual color to no avail. For a proper review I guess I should have my son put it on and take a picture in daylight. But they do need to change the color name at least to "champagne tweed" or something. No idea whose job it was to call this color "celery". ;p
