What should i do????????

Lately i've been called by a famous model agency several times, they wanted to take me as a model. I do love fashion, but i think i'm just too much of a goth tomboy and i'm still studying! (i'm a straight A nerd) My friends coerced me to accept them, and my parents together with my guy buddies disagree all the way. Sometimes i want it for some pocket money but i just don't think i can see myself as a model..what should i do? Let them wait or just reject it?
