This bra extender works great!  It fits perfectly on my 3 hook bras and gives me that extra length that I needed.  Much less expensive than purchasing a new bra if you tend to go up and down in size.  It's comfortable so I don't even know that it's there when I'm wearing it.  I also have the 2 hook extender which works just as well.  It's a very sturdy and durable product and expect it to last quite a long time.  Good stuff!  :)  Definitely measure the width of your bra hook closure to ensure that the product is going to fit!  Bra extenders come in different widths to accomodate the width of your bra and number of hooks.
