AITA for wearing the “joke” bikini my friend got me?

So it was my birthday couple months ago. Had a party. Got some gifts. My friend “Mandy” for me a “super cute bikini”. I liked it. Said thanks. She had ripped the tags off but whatever. <br><br>Anyway. Went to the community pool with my roommate. Wore bikini. Got in the water. Roommate immediately is like uhh girl.... I look and see that this bikini is now kinda see thru. <br><br>Haha good joke Mandy. <br><br>Anyway, Mandy invited me over to her place to hang out with her and her bf and a few others. Most leave and we’re still hanging out. I’m like hey, what if we get in your hot tub? I go change after them. And meet her bf in the hot tub she’s getting new drinks. I hop in. Immediately, he’s looking at my chest. I pretend I don’t notice and just make small talk. Eventually, Mandy comes out and she just looks at me in horror. I act like I don’t know what’s wrong. She’s like uhhhh Wear shorts or something if you’re gonna get in the tub. I’m like oh, didn’t know it was see thru like that. <br><br>Anyway. She’s been pissed at me for a while and won’t answer any of my texts or calls. I’m like I don’t get why she’s so mad at me. I was just trying to get back at her for trying to make me look stupid at the pool. <br><br>AITA?
