There's no better promotion of your yoga book than two absolutely stunning celebs battling out for Best-Dressed at the launch.
So Mandy Ingbera must have been ecstatic when SELF magazine got the likes of Jennifer Aniston and Kate Beckinsale to be there at the big reveal of Yogalosophy: 28 Days to the Ultimate Mind-Body Makeover.
And weren't they the perfect advert? Both ladies simply wowed in their different takes on the LBD. Jennifer played it fun and flirty in a flared mini peplum number.
While Kate was super-sleek and sophisticated in her fitted one-shoulder frock, which she paired with an equally elegant updo and on-trend nude heels.
Favourite? Ms Beck's edging this one for us.
