LOVE these extenders! They saved me so much money during my pregnancy by extending the life of my existing bras. Maternity clothes are ridiculously expensive and the bras are no exception. I highly recommend these extenders. Just make sure you get an extender that has the same number of hooks as your bra. Although admittedly I did use a 2 hook extender with a 3 hook bra for awhile. Its a little awkward, but still does the job just fine.
