Lara over at yarnit.typepad.com made her Flair using BSA Cotton in Stone. She says she tried it on as she knitted and ended up with a size between the X-small and the small (I love it when people try on as they go--then they get a better fit). Lara made other mods, too, like adding more buttons and buttonholes. She also added some increases to the sleeves so they have more flare.
Cool.
