some cursory snooping suggests that the cast did a photo shoot for a 15-20 page editorial/photo spread to appear in the february issue of vogue. one suspects karen will be in that.
i honestly don't know. i stumbled across a blog by sam rogers awhile ago. he was purposely vague, presumably due to contract reasons. but it seems that him and nine other castmembers (assuming he was speaking of WSS, unless he's premiering another broadway show) went. one of those is probably joey haro. i can't imagine that they would do said shoot with two ensemble members but none of the principals, but who knows? he did describe them getting coif'ed up a la 50s, so it seems reasonable to guess at least some of it will be in costume. the lavender dress is so iconic it seems almost remiss not to include it, but again, but who knows?...
When I've seen him onstage, it's always looked to me like Cavenaugh was on the short side. Maybe he is 5'11", but he hasn't looked that tall to my eyes.
