I have had some new suit trousers taken out by one inch at the waist. However, as I have narrow hips, this has resulted in excess fabric around the seat and hips, behind the pocket opening. I asked a different tailor about this but was told that it isn't possible to correct this and fabric can only be taken in below the pocket seam (which is below the area where the excess in problematic). Is this correct that it isn't possible to do anything around pocket height? Also, is there any way of getting trousers taken out at the waist without causing this problem to occur?
