Shopping

So 2day I went shopping and didn't buy so many things(I'll post what I bought later) why? cuz I don't fit in any sizes.! why are all things soo freaking big?!O.o Is everyone fat?? the smallest size most stores have is size 34 or XS.But that's too big for me~! can someone answer me if you think  my measurements are normal?   waist:50cm and hips:75cm I think I need to buy children clothes ^o^
