It is assur for both Chukas Hagoyim AND tznius.
i’m not gonna ask about the tznius part because i have honestly no idea.
but the chukas hagoyim?? why is it that every-day activities are suddenly deemed “chukas hagoyim?” maybe driving a car is? the goyim started that. or how about wearing pants? way back when we all wore those robe thingies. (ok maybe not the kohannim)
give me a break. like i said, maybe it’s a tznius issue – i wouldn’t know. but don’t start with chukas hagoyim. that’s not an issue.
