Yeah vanity sizing is very common in Anglo countries and especially Germany. I had a shirt that was supposed to be a UK 12-14 (US 8-10), but it ended up fitting like a US 12-14! This store was based in the UK, but manufactured in Germany, and one person mentioned on a website before that German sizes ran huge, but I didn't believe it at the time! Kept it because I liked the shirt lol. Also, I usually wear a US size 8 in dresses, but in standard sizing chart, I'm considered a 10 in tops and a 14 in bottoms! UK would be a 12, but their tops would be a 14 and bottoms would be an 18! And this is one standard chart from a decade ago! The one from '31-'55 would consider me their 20 and 40 (their sizing was weird =/), the standard size chart in '71 would consider me a 16 or 18 and the one from '95-2k1 would consider me a 12-14 and 16!
