My husband's istant looks like a sl*t. what should i do?

my husband is a dentist. when i went to visit him recently, something disturbing came up. his new istant/receptionist stacey had this mini plaid skirt and a tiny cropped top that shows the entire belly and even some under. it was such a disgusting outfit that i told my husband to fire her or get her to change, but he said it's for appeal and she's helping his business. he ured me nothing is going on. i'm very worried though
