Help me, Groupthink. How do I make the chub rub stop? I don't want to wear tights under my dresses all summer.

Thanks to a tights mishap and an especially humid day, I have a giant welt (rubbed so raw it got blisters! yay!) on my inner thigh. My thighs and I can't take this summer abuse anymore. Please, please, please tell me there's a way to make it go away.
