Ive seen a pair of Thavars for sale on the US online store that I have been wanting for a while. Unfortunately they don't have my 30x30/32 size. Does anyone know if the 28x32 is likely to stretch at all? I am not just talking about the waste. I tried on a fresh pair of Thavar 829b in 29x32 in London this weekend and they were tight around the waist and also in the thighs. Is it likely that I would get away with this?
