Shame on you!
I hope for your sake that it all blows over, but this should be a lesson to you in pilfering clothing that simply doesn't belong to you.
Get your own clothes. And tell her you're sorry.
As uncomfortable as that may be, you owe it to her, and to yourself. You need to display what you're made of, and there's no worming your way around it. Be a bigger person, make it right, and NEVER do it again.
