I had the good fortune of finding an Oxxford suit in impeccable condition and in my size this weekend at a local thrift store for $15. The only real issue with fit is that the sleeves are about an inch too short. This may seem basic, but how do I tell whether there is enough material to lengthen the sleeves a bit? I know I could ask my tailor, but I wanted to be forwarned with a bit of knowledge before I visit him. If the sleeves can't be lengthened, I'm only out $15, so I figured it was worth taking the chance. All replies are greatly appreciated. Thanks.
