I recently bought some shirts from J crew in a medium, I used to wear a small, but the chest pulls a bit. Anyway, I used to be able to wear the shirts either tucker or untucked, and the length wasn't an issue. The mediums seem to be a bit long, and a bit too wide in the waist area. Do you guys ever get your shirts shortened and taken in a bit? If so, where should a shirt fall to be okay to wear tucked or untucked? Any info would be great.
