Girls, a college classmate of mine casually showed me her underwear. What does it mean?

So this girl from college mentioned that her underwear was hurting her and casually showed me the skid marks she got from them. I'm thinking that she feels comfortable around me as a friend, but she's always trying to get physically close to me and is always attentive when I need something (a cigarette, a drink, etc) and teases me a lot, so I'm unsure. Any thoughts?

I'm genuinely much more comfortable around my guy friends than I am with guys I have crushes on. If it were me I could only tell a friend about that stuff, but some girls are way more confident than I am and the fact that she's quite quick to tend to your needs suggests she might like you. But it depends on her character.

Sounds like she is testing if you like her. It's kind of like when a girl bends over in front of a guy or has a little extra cleavage going on. She wants to see if the guy notices or finds her attractive.
