I just recently bought two Charles Tyrwhitt Oxfords off ebay for $30 shipped. Overall, I'm pretty happy with the way the chest and shoulders of the shirt fit. The only dilemma I have concerning the shirts, is the extremely long length of each shirt. Both of the tails of the shirts go way past my backside, hence causing the effect of appearing to wear a diaper when tucking in all the excess material. Is it possible for a tailor to shorter the total length of a shirt by about 3-4 inches? How much would an alteration like this cost me?
