Sienna

Sienna stands five foot eight before the heels go on, and she has never once tried to make herself smaller. Polish, fair and blue-eyed, she has the easy, upright posture of a woman who is comfortable taking up room — and who makes the person next to her feel the same.

Couples are her particular talent. She can take the lead when a pair would rather someone did, or sit back and let the evening come to her when they want to set the pace, and either way nobody in the room ends up feeling like a spectator. One to one she is just as relaxed. Duos with another companion are not something she offers.

Her taste is clean and put-together: Alo for the gym, Revolve for a night out, and a Sephora bag never far away. Ask what she is drinking and it is a Coke Zero or a Perrier. If you want to arrive with something, peonies will make the point — roses too, but peonies first.
