Do I have reason to be mad?

A couple months ago, I gave some of my nice clothes to my friend because she doesn’t have much and because I felt bad. Like name brand stuff. And today, she posted on Instagram that she’s selling clothes and it included several pieces of clothing I gave her. This irritates me because I gave nice clothes that I could’ve used and worn. If I would have known she was going to sell them, I would’ve thought twice about giving her my nice clothes. Do I have reason to be mad?
