no its chukas hagoyim
I don’t get your question. Are you asking it based on a tznius angle or on a chukas hagoyim angle?
In any event, I know that pointing this out will only brand me as a heretical unbeliever, but non-Jews also wear shirts with sleeves. And hats. And socks. And ties. Perhaps we should dispense with those as well?
Nonetheless, if you think they aren’t tznius or are in violation of chukas hagoy (however you came to that conclusion) then, by all means, don’t wear them.
