Communication is key - if something he wears makes you uncomfortable, then let him know, but do it constructively! I wear nightgowns to bed most nights, and I had one that was mid-thigh length, white satin with a sequin-encrusted bodice. After I had worn it a few times my wife mentioned that she didn't like the way I looked in it - that she prefered the longer ones, and no sequins. So, off it went to Goodwill! If she had just said "Get rid of that one!" or something along those lines I would have been defiant, or upset, or some other emotion but by letting me know that other options were acceptable to her I was happy adjust.
If your husband is wearing things that make you uncomfortable then offer some alternatives. You sound like you could possibly accept dressing if he changed his style so help him find a style more acceptable to you. If you find that you just can't accept him dressed up then you might want to discuss giving him some alone time so he can dress up while you go out with friends or something...
