So I had orginally decided not to buy anything as none of it really seemed like something I'd wear and/or use, HOWEVER, I went to some stores today with my girlfriend and she mentioned that they have a Katy collection at claires, which I had known about but never seen. Went to our local one and walked right past it without realizing it, we had given up and were walking out and run right into it.
I bought the silver "Let the light in" triangle necklace. Love it and plan on wearing it everywhere, only problem is the clip is hard for me to do but I'll manage. Also bought the Roar phonecase. When I saw the photo online I thought my current case and some previous Katy cases were better, but when I saw it in person and saw that it was holographic I immediately grabbed it. Only problem I had with that was the jewels on the side. Was debating on popping them off, but I kinda like the feel of them when I hold my phone, having the bumps there.
Also I have now converted my girlfriend to Katy Perryism. She loved all of the jewelry there and ended up buying the unconditionally ring. Played the song for her when we left and she loves it. I left her in my van with it running and green day playing through my phone so I could go inside my house to grab something, I walk back out and she had changed it to Unconditionally XD. She is now one of us!
