If you're discovering the world of ABDL clothes, you'll be surprised to see that near everything exists at your size.
I'm a big fan of Privatina. Well, it's more expensive but it's hand made build exactly at your size in Europe (Poland).
I own two footed pajamas exactly at my size, one in terry cloth and one in cotton. Once they have your size (and they ask for a ton of different sizes, like the lenght of your feets), it's easy to get any other model, just "build" your choice and after 2-3 weeks you have your own one at your own size.

Note: I washed them several time including the dryer and it didn't move! Good quality.
