My female friend wants me to do cross dressing for modeling should I do it?

im gay but I don't act fem but I can act girly and walk like a girl and that's my female friend likes she's an assistant director of runaway fashion modeling this weekend, they will going to have fashion show but they need one more model, but they can't find one available. should I do it? I like to try to wear some woman's clothes and those super high heels shoes hmm. She also said that if I could do this for her, she can help me to apply for men's fashion and photography so I can be on the fashion magazine which I really like. Do you think this is a good idea?
