I ordered this suit in 33 waist with 40 short jacket and vest. I got short because I don't like long sleeves and a long tail on my jackets; looks more tailored I think. I am 5'9 1/2 and weigh approximately 170 lb. My Brooks Brothers suits Jacket sizes are anywhere from 38 to 42 depending on the cut and size 32 to 34 pants for reference. I think because it's a athletic fit I had to go up to a size 42 short jacket with 34 pants. I called about doing an exchange and got a live person on the phone directly. Imagine that no prompts and connected directly to a live person! Within 2 minutes, he had my original order return label emailed to me and had my exchange sizes ready to be shipped out. There was a hold put on my credit card for the amount of the suit until my return package was received by them, which was perfectly acceptable with me. No wait time. I received the next suit within 3 days. There is a few minor alterations such as length of pants which is normal when buying any suit but also in the upper thigh area they were a little baggy so I had them taken in slightly as well. The suit was packed well in a nice box. The colors are the suit matched the images on the website. Absolutely a great suit and customer service. 100% I will be a repeat customer.
