I have some TM Lewin casual shirts with checked pattern and a pleat on the back. What would the best way to have these slimmed? I have never been to a tailor but want a idea if what's going to be done. I don't know if darts are a problem with patterns, and most darted shirts don't seem to have the pleated back. The collar and arm length of these shirts is great, so I'd rather have them tailored slim rather than sent back for a refund since they came overseas.
