Hi everyone, I've been wearing a nice Yves St Laurent three piece suit for the past two years and have gotten a lot of use out of it (and hopefully more to come). However, I noticed yesterday that one of the stitches in the back has started to come loose. At the moment, there is just a small loop hanging off, but I want to nip this in the bud before it gets any worse. Any suggestions on what to do? I'm in China now and trust the opinions on this board over what my choice of local tailors might suggest. Thanks in advance!
