You are 16 years old male and you want to buy girl clothes and lingerie how do i buy items without my parents knowing?

Hi, I'm in the exact same spot as you. I get around it by going with my girlfriend and claiming that I buy her the dresses and Bras and whatnot. Then, the next day, when my parents are gone to work, I call her and ask her to bring them over.

Or, you can buy the stuff, and hide it until you know you can get it home without getting caught. Where you do this is up to you. That's why I suggest you have a girl that you don't mind knowing your secret help you. That's a big help right there ;)
