It’s barely gotten cold outside, and the fashion world is already thinking about spring! And you’ll never guess what some fashion houses are offering for spring: Bra tops.

If you haven’t seen or heard about this, Versace, Dolce Gabbana, Donna Karan and more incorporated “fashionably sporty” bra tops into their lines for spring 2012. The tops feature thick straps, elastic bands and sporty cutouts teamed with full skirts and jackets. Some can be worn over dresses, and there are strapless options, too.

Fashion reporters say the trend has a “retro” feel to it and will provide endless options for layering. A glimpse of this fashion trend had some of us at CupCase thinking about doing a few thousand crunches and buying a ticket to Hawaii where we could try out the new trend without running into anyone we know.

Let us know what you think about bra tops for spring. Is this something you might try?

In other news, it was just announced that supermodel Bar Refaeli (who used to date actor Leonardo DiCaprio) is going to launch her own line of affordable underwear. The collection will reportedly include selections for women and men, and it will focus on comfort.

We like that idea, as we all tend sacrifice comfort in the name of fashion. And because we also sacrifice a lot of green for fashion, we like that Refaeli’s line is supposed to include basic items in the mid-range price sector. The line will be called Undeez and will be available in Europe in early 2012 and the U.S. in late 2012.
