Hello, I'm looking for a vintage suit to wear at my wedding. Ideally 1960s, single-breasted, but open-minded. Preferably not too thick or heavy. Two or three-piece. Has anyone any suggestions of where to find such an item? Have been to Brighton lanes - good selection but couldn't quite find the right one.
Thank you! Ben

There are many vintage shops in London. If I go into one and have a look around what's the best way to assess whether it's a quality shop and worth spending time and money on?
