Poor Quality
This suit was for my nephews school dance. The look is great however, its not of good quality. The material is cheap and looks as though it should be a costume. When my nephew tried it on it looked baggy. I returned the suit but have yet to receive a refund.

Awesome Suit!!
I purchased this suit for my boyfriend to wear to a party. I ordered an XL, he is 6'6" and 230lbs, initially the fit was fantastic and looks amazing but after wearing it and moving around in it for about 30 minutes, the pants started to slip down. The fabric has quite a bit of spandex in it and tends to stretch out after wearing for a little bit, it fits great right after it has been dried but then stretches out again. I ended up taking in the waist a little bit so the pants stay up, a large would likely have been a better fit. But he always looks amazing when he wears it and gets lots of compliments on the fun pattern. Definitely worth it!

Great suit!
Size: X-Large, Color: Navy With Blue
I was pleasantly surprised by the quality of this Mage Male dress suit. The material feels very soft with a velvet-like texture that makes the entire outfit pop without being over the top. This suit is perfect for prom, weddings, or any event where you want to elevate your look a bit.
Sizing was accurate for me, so make sure you follow the size chart closely. I recommend picking up an inexpensive tape measure here on Amazon to double-check your measurements — it makes a difference. For the price, this suit is absolutely worth it and I’d buy it again.
