Satisfied Sneaker Head
Size: 7.5, Color: Optical White
These are my 6th pair of Cole Haan shoes and probably my favorite. They're light weight, comfortable, well built, and beautifully designed.

True to size
I purchased this suit for my son’s prom. The jacket was a perfect fit but the pants were a little big on him. He loved the jacket. He said that the jacket was comfortable and roomy. We also had to have the arms taken up a little bit. The color and quality were very good!!! I myself loved the design and the material. Very nice.

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.
