A girl tells you her size?

I suspect my coworker is into me. She visits my cube daily and likes to share small chat. More recently she’s asked me about her recent haircut and now, she told me about buying new pants. She began twirling and modeling it for me, and she randomly offered her sizes (small top, size 9 pants and 8 shoes). Why would any woman randomly offer this information?

She gave me her phone number without me asking. I think she likes me. I told her we should spend some time together. If anything, I’ll make a new friend, maybe someone more.
