I am a pretty thin guy and normally buy the extra slim shirts from Charles Tyrwhitt. For the most part, these shirts fits well. However, it seems like the classic fit shirts have a much a larger selection and I am tired of buying whites and blues. If I were to buy some classic fit shirts from them, could I get them tailored so that they fit the same as an extra slim shirt? I am not sure if there is a limit on how much a shirt can be taken in by a tailor. If I buy some classic fits, it seems about 3 to 3.5 inches from each side would need to be taken in.
Thanks again for the advice
