I am a 5'9", approx 155lb woman. I ordered a medium suit. The jacket and vest fit perfectly and I was very impressed with the appearance. The only problem was that the pants were hilariously small on me. When I contacted the seller with my measurements, they happily sent me replacement pants. I am overall extremely pleased both with the suit and with the service I recieved. I am looking forward to an occasion to wear my new suit.
