Dont like purses?????????

Hi Im 13 years old and I Just got the Iphone. My mom is MAKING me carry it in some sort of bag, because its glass and all and because i am a klutz and I will probably drop it. Do you know like a small tote bag? Like its open and stuff and its not this little ugly mini purse type thing?? (me and the guy I like are hanging out nd if I wanna bring my phone with me, i have to carry it in a bag and I don't want it to be embarrassing, especially around him!!) thankss!
