Was it weird that she told me this?

ok. there was this girl that i have been crushing on forever and we were in the lunch line (it was pajama day at our school) and there were 5th graders wearing a robe for pj's and i said "who wears a robe to go to sleep in?" and she looked at me and said "i know right? all i wear are these shorts" and she pointed down. and in amazment i tripped over my words and said"hopefully u were something above that." and she kinda stuttered and said,"well and a bra" she said it like really slow and like it was a lie. so is it weird she told me what she wore to bed? and is it weird that she may only wear a bra? and does it sound like she likes me at all?
