What should I wear? School pictures are today!?

Okay. My name is Amsedel, turning 14. Okay today is picture taking. I do not know what to do. And everyone please help because TODAY is picture taking!!! Anyways, I'm thinking a simple sleeveless shirt with very little design. it has ruffle on the top. It goes from E-W not N-S. It is also brown. Anyways. I'm not sure if I should wear a sleeveless shirt, but all I have are sleeveless. I have short sleeves but they are PAJAMAS >.< erg. I don't if I should wear it because the other kids might think I'm trying to impress someone. And yeah.. The whole outfit is a brown shirt, skinny jeans, and cute sandals. I know half of my body won't be shown but I still will be in orientation today, and I want to look nice. Oh I forgot to mention, imagine yourself wearing my shirt. And then you fold your arms. Right above it is the ruffles. I think its pretty cute :) Anyways. If you guys think otherwise, please note down a cute outfit for picture taking. Thanks guys and remember the Picture taking is TODAY! Please help! By the way Im asian, but I have brownish/black hair and I don't have those asian eyes.. No offense! And yeah. Please share your comments. Thanks BYE!!
