Makeup and girly stuff type of question...

C
Hi, so I've always been the type to wear minimal to no makeup at all. The most I wore was a bit of concealer to cover up my redness and blemishes, however I am turning 18 tomorrow, and I'm tired of looking like Imm 10 years old. I want to wear false eyelashes, however I'm not quite sure if they will mess up my real eyelashes? Does anyone know if I wear glue on eyelashes they will harm my real eyelashes? Also what's a good way to start off? And change my way of dressing. I usually wear casual clothes like fandom shirts with jeans and stuffI just want to be more girly for myself. Any suggestions on how to start? Thanks ❤️
