They all got professionally measured for the final (voting is open now BTW) here are the new bra sizes.
Nicola Graveson, Edinburgh - UK, WAS 32E NOW 30G
Ashley Bridges, Woodbridge - United States, WAS 28J NOW 30K
Sophia Adams, London - UK, WAS 32JJ STILL 32JJ
Holly MacGillivray, Isle of Wight - UK, WAS 38E NOW 34HH
Emma Webley, London - UK, WAS 34HH NOW 32J
Tatiana Meilhac, Lyon -France, WAS 34F NOW 30G
Megan McMinn, Bath - UK, WAS 34E NOW 30G
Charlotte Buck, London - UK, WAS 34F NOW 30G
Rosalind Strong, Sydney - Australia, WAS 28GG NOW 28HH
Danielle Fearon, Bedfordshire - UK, WAS 30GG STILL 30GG
Which just goes to show how few of them were actually wearing the correct size bra. I must admit that Tatiana didn't look like a 34F to me, she did look smaller (believe it or not a 34F is BIGGER than a 30G, a 30G is really the equivalent of a 34E in terms of actual size).
