I've tried loads and most have major clipping issues on the neck and hands. Fine clothes were great but one of the hands were clipping out the sleeves badly. Doesn't look like they bothered testing it

I rock redguard clothes with a fine hat.

They are good but if you look down in first person, you notice floating hands. There is a big invisible gap.

I always thought a collar looked good on them.

I like going around in just Ragged Pants, lol.
but yeah a lot of Clothing & armor kind of messes up on Beast races.
I guess the clothing that sort of looks like Link's Tunic (Brown or Green, there's 2 of them) looks fine, or the Party clothes you get from Diplomatic Immunity quest.
Circlet's work good for head-wear, and Imperial light Bracers work good for gloves, doesn't re-shape the hand like most gloves do.
