I can't find a word that rhymes with "jubblies"

My work environment is very, very casual. My usual work uniform is jeans, a t-shirt, and flip-flops—and yes, I work in an office. Chris’s office, on the other hand, is more formal. The normal uniform for men is a long-sleeve button-down shirt, tucked into dress slacks, with suitable shoes. So this morning, I was surprised to see that he had paired a more casual button-down with jeans. He reminded me that on the occasional Friday, they can pay $5 for the privilege of wearing jeans to work and all the money goes to charity—this week it’s to support breast cancer research. Sadly, they have no catchy slogan to promote this fundraiser, so I proposed “Dungarees for Double-Ds.” After snickering, he countered with “Dockers for Knockers,” which naturally spawned a whole conversation during our morning commute. How about “Pajammies for Mammies”? Or “Vests for Breasts”? Or “Tube Socks Cuz Boobs Rock”? "Mittens for Kittens, You Know, the Ones You're Smuggling"?

I tried to think of something involving hats and racks, but that fell flatter than Lara Flynn Boyle’s chest.
