I was considering whether to buy this bra or the Medela bustier, which was a few dollars cheaper. I'm so glad i got this one. It has a long velcro panel in the back, which makes the girth adjustable for many sizes. It also comes with a zipper front panel, which can be inserted depending on the spacing of your breasts. I also really like that it has straps. My breasts are heavy with milk and the straps provide me with the support that I need. I am going to order another one. I definitely recommend if you have the Medela Freestyle Handsfree pump.
