Schöneberger Trachten Couturemens Alpenjaeger Classic

I purchased these in us size 48 but was sent eu size 48. i had to return them. how can i make sure that i will get the us size when i order??

I wear a jean size waist 34 and length 30, which lederhosen size would you recommend?, should I go 2 sizes up?

Do you accept returns?

Are these lederhosen sized in us sizes? i see you carry a 52? is that a regular 52 waist for big men or run size?
