* sneaky suspicion merkins are in play here. Sarah and Michelle - IMHO - are wearing patch-ons. Anyway nice lingering shot of the girls. Too bad Sarah waited so long to show it. At 41 - typically saggy. At least it's natural. The patch on merkin is quite effective. Mary-Louise Parker in “Angels In America” and Rooney Mara in The Girl with the Dragon Tattoo are best instances.
