Okay, seriously... I went to two bridal salons yesterday to try on dresses and at both salons at the end of the appointment while chatting with the attendant, I WAS THANKED FOR WEARING UNDERWEAR, and BOTH women said, "you wouldn't believe how many come in here with no underwear!"
They seemed really creeped out by it, and I don't blame them since they are reaching blindly up under the skirt to pull down the under layers of the dress.
