Pretty good suit
Size: X-Small, Color: Beige
These suits are great. My groomsmen wore them and everyone looked so sharp. They may need to be tailored to get a good fit for some persons though

Gets the job done.
Size: Large, Color: Deep Blue, Size: Large, Color: Deep Blue
Better than I expected (for a last minute buy). Looks great after I steamed it. Not the most durable, but a solid piece for the price. Thick and breathable material. I’m a 42R and the fit was perfect with no alterations needed.

Great fitting suit!
Size: X-Small, Color: Deep Grey (Stretch Fabric)
If you’re 5’8” 145lbs this review may help! I’m 12-14% BF, range 142-150lbs, 28-30” waist. I wear 30” inseam for pants, 40R suit but can fit 39R, 15/32 slim fitted dress shirts, small to medium fitted T shirts. I love the fit of the suit. The grey color and the texture of the fabric could be a little better. Seems the fabric isn’t a solid consistent look. A little textured I suppose. The jacket fits well and I love the stretch fabric for the armpit area. Makes it easy to put on and move around while giving a good fit. I think a little bit more room in the shoulders would be nice. The cut is a little off for me in the back of the jacket by the neck area. The vest seemed a little large but has an adjustable strap in the back. For the jacket pockets, you’ll have to carefully cut and pull the threads at the opening since they are sewn shut. I did notice a little wrinkling to the side front near the serratus. Could be the cut. For me if it was a little roomier by chest and tappered in more it would fit better. The joint where the sleeves meet the shoulder are OK. There are some wrinkles there due to imperfection with stitching. The sleeves come down past my wrist a little. My arm-span is square with my height for reference. If you have big biceps it might be a little tight. The pants fit perfectly for me. Good length with no excessive break when not wearing shoes. There’s some excessive break when wearing higher profile shoes. The stretch waist is nice for when you decide to eat and drink too much and still comfortable while sitting. I’ve not found a slim fitted suit like this before. Comfortable to dance around in also. If you have thick thighs it might feel a little tight. Wore the suit to a wedding and it was great. Can’t really complain for the price. Good luck!

Tie color, general review
Size: Small, Color: Grey
Great quality, love the thickness of the suit wearing it in the summer it wasn’t hot. Nice buttons, love the small extra gift. Would prefer a neutral colored tie that could go with anything rather than the red and white striped they offered with the suit. Pants fit a bit bigger, had to adjust it to my measurements but, all by all a good purchase!

Nice material, stitching. Fit was unorthodox.
Size: Small, Color: Light Grey (Stretch Fabric)
putting on the suit for the first time, pants first, I thought that I had gotten a steal of a deal! The fabric was of good quality, had a good amount of stretch and was just long enough for my long legs. (typically wear a 32/34, but cuff the jeans once). It was the top section that I had an issue with. The shape of the shoulder-to-neck area was very pointed. As someone that has almost no trap muscle, this meant extra fabric that sagged on the my shoulders and gave me an unkempt look and I'm not sure this is something that a tailor can fix easily. If you have a little more beef up top, this would probably work for you. I wish it would have fit differently because I was impressed by the quality.
