This "bra" is a must have for using a double pump!

I first bought the Medela one in the store with the pump, and it was completely useless.  It didn't fit right, had no support for my somewhat large chest, and you had to separate the flanges from the bottles to remove them which resulted in milk everywhere.

The Simple Wishes is adjustable to a huge range of size, including an optional panel in the middle to space out the holes.  It includes straps which I use in a halter configuration for added support.  And most importantly, you can insert and remove the flanges while keeping the bra on and the flanges attached to the bottles, so no milk is spilled.

Make sure you check the size chart - I was skeptical buying the small/medium (I'm a 38D) but it does really fit.
