office gift giving

When I got back to the office, most of the staff had left and the receptionist handed me my Secret Santa gift. I took it home with me and opened it up on Christmas day. It was a $50 Victoria's Secret gift card. The note read: 'Whatever you choose, you will look great in. John." How should I handle this sticky situation?
I am a recent graduate who has landed her first management position. My boss is great and I have an amazing team of three under me. I would love to show my appreciation to them all this holiday season but don't want to give them the "wrong" kind of gifts. What would be your suggestions?
