I've always loved the naked for the delivery guy. Order a pizza or something to be delivered. Act like she just got out of the shower and wrap a towel to answer the door. Turn around to set the food down and OOPS towel falls off.
That's what I'd do if I were a young hot girl, like your girl is.
Also I would wear revealing see through shirts with maybe a cover up jacket and then let it open a lot for when you're out and about.
Have fun! Life is too short. Enjoy it while you can. Don't waste your youth being scared of what people might think. Plus the youth seem to get away with nude antics more than older people.
