Prom Must Have
Size: Large, Color: Black, Size: Large, Color: Black
1) Totally affordable compared to ANY rental
2) Prom or Homecoming, maybe a (non high fashion) charitable event type quality jacket. True to size.
3) Pants are likely a 36” length. But otherwise true to size. The quality is great.
4) I ordered according to another review. My son is 5’10” plus a smidge. He’s 180#. Athlete. I ordered a Large. It’s perfect other than the length. He has a twin brother who is the same height but about 20# lighter and would need a medium. Also an athlete.
6) Make sure you order in time for pants length alrerations.
5) Do it. Order it for your event. Save a few hundred dollars and a ton of time returning rentals, those pants can be used again for sure.

Great suit!
My man looked soooo handsome in his suit. We ordered this suit at the last minute. It fit perfect. He is 6'3 wears a 38 jean and xl shirt. We were worried about the length of the pants but they perfect and long and the jacket fit perfect! The quality was great and he said he loved the fit and it was spacious. We went to a ball and we leaned and rocked all night and he didnt have to come out of his jacket to do so.

The blue really pops
Fit fine, looks great, just wish it came with a tie. It does not come with a vest or shirt either but I didn’t really care about that. Pants were a little long but once my son put his shoes on he was able to manage length.

tuxedo
I bought this for my son for my sister's wedding.
The pants were way too big but we knew that when we ordered it.
We bought the correct sized bottoms and he rocked it.
