Mommy Femme Bot
There isn't much sex appeal associated with pumping (I believe Jon let out an extended, definitive, and less than supportive "mooo!" when he first saw me pump), but if you’d like to feel - as a mama pal describes - “vaguely like [an Austin Powers] femme bot” (while pumping efficiently of course), try the Easy Expressions Bustier.
A terrific pump at work solution, the bustier makes hands-free double pumping easy through a strapless, zip-front design. Available in small (32-34), medium (34-36), large (38-40), and extra-large (42-44) for $33.95 (see the Breastfeeding Accessories section of BabyCenter).
