Shopping for size...

I'm a European size 40-42. Will i have trouble buying clothes in Japan? In say, the trendy shopping malls like shibuya 109 or Marui?

Thanks for the input~

Shops Marui and 109 tend to have a very small range of sizes, usually only small and medium, which would be about 32 to 36. I take a 40 in trousers at H&M at least, and I can buy trousers only at places like H&M, Zara (where I'm a 38), Benetton, Next, i.e. no Japanese brands other than Uniqlo, which has a wider range of sizes. At most places other than the above, length is also an issue for me for trousers (I'm 175cm tall).

Basically Japanese branded clothing ranges tend to be narrow in the hips for most non-Asian women, as Japanese women tend to be less curvy. If I find trousers or skirts that fit me in the hips they gape at the waist.
