Oh man, good question. Haha so I found it in the suitcase... I guess I'd picked it up and threw it in there 'cause I thought it was mine.

The shirt was turned inside out and so all I could see was plain black, and the texture felt exactly the same as one of my shirts!

So I think I must've thought it was my black sleeveless shirt. But when I was packing my suitcase to leave, I took everything out of it to start from scratch.

I turned the shirt back the right way and that's when I was like, oops. haha

I knew I'd find it eventually that's the thing
