Whitney Port and her best friend from high-school Roxy Olin share more than just starring roles on the stylish reality-drama "The City." The two also share a few fashion formulas based on their recent attached-at-the-hip red carpet appearances.

Here is a [fictional] summary of what their pre-party convo may have sounded like:

WP: So, who's wearing tight trendy jeggings tonight, me or you?

RO: You are! But I wanna wear the boots tonight.

WP: OK - but I MUST carry my signature clutch.

RO: Did we decide if we are going for a pale 60's bisque pout, or should we scream "romantic and on trend!" with neon scarlet lips tonight?

WP: Well, red will clash with my new envelope clutch, so let's do Nars "Honey" lipstick.

RO: O.K., I think I am almost ready to leave. Just let me pull my hair nonchalantly into a side-pony and grab a piece of odd statement jewelry.

WP: Great! I'll just pick out one of my many sassy hair accessories and we are all set!
