Do they sell kids clothes by age where you are? In the UK they do and even today, I had to peruse the kids clothes at a market because they are the only ones that would have fit me. The same stall had TONS of UK sizes 16, 18, 20 , 22 and up, a quarter of a rail of clothes from size 8 up and nothing else. I can wear size 8 but it's too big on me and I like to wear my clothes fitted. I wear UK size 4/US 0 and UK 6/US 4.  I am 25 and can wear age 11-12 and up, I don't want to look like a little girl so even then I have a limited choice unless I want My Little Pony all over me, it is so demoralising sometimes but cheers me up other times, we are adult women should never be able to wear children's clothes yet here we are. At least it is something that we could shame fatties with!
