2. Charlize Theron at the 2010 Oscars
Charlize's lavender Dior dress with bustier roses received mixed reviews but was impossible to forget. Designed especially for her by John Galliano, the gown was particularly memorable because of those floral details, which many thought drew too much attention for the wrong reasons. The actress certainly didn't need to show any cleavage to get everyone talking about this look!

With its strapless design and flowing train, this could have been a classic. Amazing how one little detail completely steered this in the opposite direction!
