Katy Perry was the first to wear this beautiful Temperley London gown back in April while attending the 29th Annual ASCAP Pop Music Awards.

Her sheer ivory gown with intricate embroidered details was worn with a strap off the shoulder, a delicate floral garland and a stack of complementary pearl bracelets.

Ashlee Simpson offered a more angelic feel to this elegant gown when she attended HBO’s 2012 Emmy Awards Post Awards Reception last week.

Even thought this sparkling gown doesn’t need too much accessorising, Ashlee added an oversized Judith Leiber clutch, but kept the jewels minimal.

Ashlee wins for me as I don’t like Katy’s rock-chick interpretation of this look.
