I buy a lot of clothes off eBay, so having a good tailor is a must. Fortunately, I've found an amazing tailor at Zizzo. I barely have to explain what I'm looking for and they nail it every time and if I'm not 100% satisfied (which has happened only once because I was being indecisive the first time around), they fix it. No hassles.
They're also a joy to hassle web you're in there. It feels like the real, authentic tailoring experience you'd have expected fifty years ago. I can't recommend them highly enough.
