Owner of the bar I work at told me I should wear “more skimpy outfits” for better tips

I work part time at a local bar and the owner is an older guy. He probably comes in once a week to check on things. I already wear outfits that are pretty tight and/or revealing (tight dresses, leggings etc.) Anyways, the other day he came in to check on things and and he told me “if you wear more skimpy outfits, you’d get more tips”… I didn’t even know what to say back to him at that point.
