I like to wear form-fitted shirts and men's cargo shorts together. It was my signature look for a while. Then I got all paranoid and self-conscious about my legs. So I wear pants (or skirts with leggings or anything that keeps my legs covered) all the time, except on vacation and during the summer, during which I go back to my happy little combination.
Wearing just a shirt and underwear is fun if I'm trying to get attention.
I do some modeling for art classes, too, Petit! I've only gotten to do it twice so far, but the second time, I was in a bikini. You don't truly feel self-consciousness until you notice that someone has carefully crafted a sketch of only your butt and thighs because of the pose you were in (I was in this big stretching-like position, where the people behind me could basically only see my butt and legs and maybe the back of my head. I still haven't decided how okay I am with this.
Welu, are you talking about storing those photos on your phone or computer? If they're on your phone, then you can transfer them to your computer and delete the copies on your phone. Storing photos on your computer is really easy--find a folder you never use that has a bunch of things in it. I took a folder I had downloaded for a school project. Then, make a new folder with a title that blends in. This works especially well if the other folder titles are gibberish. Make some folders inside of your new camo folder. Bury your folder with the actual pictures as deep into that as you like. I keep a few folders in there of outfits (mostly nighties) I thought I looked good in. If you're not planning on sending them to anyone and take care of your computer in such a way that it won't get stolen or snooped in, then you should definitely be fine.
