Mod is in, and it looks like Rihanna and actress January Jones got the memo. Both of the beauties wore this itty, bitty checkered getup for magazine shoots, but which lady do you think looks best?

Rihanna rocks this retro look in the April 2013 issue of Elle in the U.K., while the blonde 'Mad Men' starlet dons the black and white, two-piece set on the April 2013 cover of U.K. Glamour. The '60s-inspired design is by Louis Vuitton, and the crop top and mini skirt combo shows off both RiRi and January's toned abs and gams.

Who do you think looks best in this flirty, vintage look? Vote for Rihanna or January below!
