January Jones loves a sexy (and sometimes risky) style.

Just last night the Mad Men actress stepped out in a black and white Roland Mouret dress that had cutouts in all the right places for the AMC show’s premiere party. She paired the look with Cartier earrings. 

But this style reminded us of her red dress that had everyone talking after the 68th Annual Golden Globe Awards in January 2011. 

The actress, 34, sometimes better known as Betty Draper, stepped out in a SUPER sexy Versace gown that year that featured, yet again, strategically placed cutouts. 

Both looks accentuate the actress’ killer curves (and cleavage), but which dress do you prefer? Cast your vote in the poll, and leave a few reviews while you’re at it!

January had a very different style at the PaleyFest on Tuesday night. Check out her baby blue, conservative Jenny Packham dress below:
