im 15 and gay i want to cross dress?

I'm around your age and straight and I cross dress, so if my parents found out they would think I am weird, but if they know you are gay it might not be an issue. I mean think about it. Even though in real life most cross dressers are actually straight, it is often(wrongly) associated with being homosexual. So I don't think your parents will thing ill of you if you cross dress and indeed know that you are gay. But on the topic of buying the clothes, you have two very good options. One is pretty obvious, online shopping. If you have your own credit card you should be able to buy clothes online, but then again that is risky because you don't know if what you purchase will fit. Your other option that is the easier is thrift stores like Good Will. These clothes are cheap and usually very easy to access. They also have very convenient dressing rooms for you to be able to try on clothes. That is where I would go to get what you want. Another option would be normal stores, but wait till the Halloween season. If you are at Target and buying a dress most of the year everyone will think very oddly of you, but if you are at Target and buying a dress in October everyone will likely assume it is just for some costume. Don't buy more than one dress at the same time though, then people might think oddly of you again, but it can be pulled off. Hopefully this helps, and just remember to have fun!

I think thrift shops are the best bet here. Lowest cost too, while you discover what you like and don't like. Your problem will be where to stash them so they aren't found. I enjoy wearing panties myself.

Buy them online you can purchase a prepaid credit card and then use that online just like a gift card and if you want ask if you can ship it to a friends house.

Wait til your family ain't home and raid your mum or sister's wardrobes.

Oh, and charity shops.
