Overall ok
Size: Small, Color: Light Gray, Size: Small, Color: Light Gray
I purchased this for my son for homecoming. 6’, 170, size S. The pants fit well, the jacket is kind of boxy. If you’re looking for a more slim fit on jacket, this is not it. It was too late for us to get anything else. Overall, it was fine. The sleeves At wrist not as crisp. I had to really press to give crisp shape. I steamed the heck out of it. My son was OK with it. Holds up well for one time use. Color was what we wanted.

Best bang for your buck
Size: Large, Color: Navy Blue
Highly recommend this suit if you’re looking for the best bang for your buck! We did go with another option, but upon receiving the suit, I will definitely keep this seller in mind for other occasions! Do wish you could mis-match the pants and blazer sizes, but still a great option if you can fit the top and bottom together! Even adjusting bigger sizes with a tailor, still cheaper than most options while not appearing as cheap as it is! Also ordered the champagne color, very admirable as well!

Great vest
Size: 12, Color: Black
Great vest. I love the slim fit. It looks very nice on my son, not baggy or boxy looking like some vest. My son has used it for several occasions including a wake, a Beta Club induction, awards day, and soon his graduation celebration at church. The quality and material are good. Definitely worth what I paid.
