La Senza presents the cup sized choir. Karmarama only picked up the business just last month, and they'ce already created this, just in time for Xmas-carols. Perhaps they had a little help checking out how oooooouch.com was made.
"Seven girls with bra sizes A to G make up the musical notes of the Cup Size Choir. Have a look, have a play at cupsizechoir.com and have a Happy Christmas."
Clearly, the campaign is aimed at men, the educate them about cup sizes before they do their xmas-shopping, women usually don't like being compared to keyboard-buttons and want to know if the EFG cups look good when the women wearing them are standing up. Go fig.
