Nicole Richie, Rosie Huntington-Whiteley (FameFlynet Pictures)Two of our favorite trendsetters,
Nicole Richie and
Rosie Huntington-Whiteley, recently wore a basic but strangely nostalgic piece while out running errands. What is it? The ribbed mock-neck tank, of course.
The sleeveless number screams '90s! Really, when is the last time you've even heard the term mock-neck? There's no doubt you could walk into any thrift store at this very moment and find at least 5 of these babies on the racks. Perhaps even some cropped options, or (gasp!) a
full turtleneck version.
Take a look at how these two took very different approaches to the same trend, which do you prefer?
