It also depends on the cut of the particular style. In most brands and styles I wear either a 28 or a 29 (I usually take an 8 or occasionally a 6 in American sizes) but I tried on a pair of Joes the other day and the 30 was too tight! And I have an old pair of Parasuco 27's that fit fine. Sizing is so weird and non-standard.
I wear a joes 27, AG in 28 and paige...any idea how Goldsign runs? I think its the same designer that makes AG. Should I get 27?28 Help!
