Harry Potter and the half-slipped nipple

We were initially so distracted by Johnny Borrell's amazing outfit that we didn't notice the fact that Emma Watson was wearing a sheer top with no bra - NIPPLE SLIP AHOY! No wonder Borrell's whacking one off under that hat (didn't she once let him poke her with his magic wand anyway?)... It's nice that the hat does at least have one useful purpose.

Borrell and Watson were at a pre-BAFTA party organised by Lancome, along with Cuba Gooding Jr, Alexander Roache, Henry Conway, Tom Higgleston, Caroline Flack and others. Great work, guys. Good luck with those BAFTAs tomorrow, all of you.
