Ordered the wrong size?- if this is underwear, then it is not possible to return, even if in original packaging- it is not possible to exchange for a different size for online purchases- you could return it, but wait , the returns portal (uniqlo.narvar.com) returns an error page- you can still return it to a shop: the nearest one to me is 100 miles away.Maybe you will be lucky and get the right size first go, I won't be buying from uniqlo again.
