Here's a universal truth for you: Men find a deep v-neck anything to be equal in excitement to a fridge full of beer and the TV stuck on ESPN. A tasteful sweater or tee with just enough plunge to entice them without showing all your wares is the goal here.
Here are two ways to give your girls a little exposure:
Splurge: J. Crew Collection v-neck cashmere sweater. I treated myself to one of these in the fall and I wear it constantly. Soft, subtly sexy, and well, cashmere. Comes in 16 fabulous colors. And now select colors are on sale! $99-$188
Save: Old Navy women's v-neck softest sweaters. Super-soft and comes in five yummy colors. My advice? Skip the cami underneath and let the sisters peek out just a touch. Really, it's OK. $15.
