This is my new Elila 1505 in a 50N. I have a very narrow back but my bust is very large and heavy for my frame. This bra has a very deep 7" back with 7 rows of hooks so a lot of the load of my bust is spread across my back. Interesting as bra adverts only suggest it has 76 hooks! The 1" wide non stretch straps have extra wide pads that be adjusted to soften the load on my shoulders. The straps adjusters are strong plastic and easily adjustable but I'm hoping they stand the test of time. I'm familiar with the plastic strap adjuster on my old Elila 1305 that Elila solved by using metal adjusters. These adjusters do allow me to raise and lower my bustline with ease through. Only a few days use so far but looking good.
I have been wearing this bra as my everyday bra for the past three years. Support style for large heavy breasts; Wide cushioned straps, support slings in cups and 6 hook back. Difficult to put on in the morning, six back hooks, getting my breasts into the cups properly, "once in", it is so soft and comfortable and the fit so secure I actually love it. No bounce, weight is off my shoulders and spread over the wide back. Helps my posture, no backaches any more. Long wearing, love this bra and recently purchased three more of this style.
