The immortal nymph was dressed nicely, in her opinion. She wore a 'vintage' - word that Walter would use for it, not herself - mustard yellow dress. Looking down at the dress, she wondered if vintage meant an entirely different thing between the pair.
The dress flowed all the way down to her shins, which in her time would have considered herself a whore. Assumed to come walking straight out of a brothel. It wouldn't have been the first time someone claimed that someone accused her of that, but it would still be a comment that would anger her in one way or another. That was her more definitive point to the dress not being very vintage.
