Sarah the Pegasister

Hello! I was hoping a fellow trans could help me. Starting at around September of last year, I was entertaining the idea of being trans, made my decision in December, and came out to most of my friends and my brother in January. I've been hoping to acquire some feminine clothing like dresses, skirts, that sort of stuff, but I'm not sure what the best way to get it would be. I'm definitely not ordering it online, as I need my mother's credit card to make most, if not all of my purchases, but my parents definitely won't understand. I don't have my drivers liscense yet, so I can't drive to the store either. Any suggestions?
