RORY: Take light layers. Wear your turquoise and tan dress that you just got that’s cool and it’ll look good without your gown on, and wear your turquoise vintagey sweater over it because it’ll look great with the dress and it’ll keep you warm if it’s cold in the auditorium.
LORELAI: You are a fashion genius.
RORY: Well, you’ve taught me everything I know.
Rory’s fashion advice to Lorelai is a callback to “Kiss and Tell” in Season 1, when a panicked Rory can’t decide what to wear for her first date with Dean until Lorelai picks out a top for her. Now it is Rory’s turn to help out her mother when she is too keyed up about graduating to select an outfit.
I’m not sure whether we’re meant to think Rory has become a full-blown fashion expert in the past 18 months, or just that either Gilmore girl is capable of getting the odd brain freeze, and needs the other to help out so they can get dressed. The shows seems to be leaning towards the former, because Rory was so stunned at the way her mother could instantly pick the right top.
Also note, Rory Gilmore’s fashion genius advice – wear layers, no headwear over curls. You got that for free.
