Hi SisterBliss. I've no idea how to do links, sorry, but if you search "Glamorise" they pop up in Ample Bosom, JD Williams, Simply Be, Just my Size, Curvissa, Damart and Look Again.
It's an American brand so uses American spelling.
I found looking at their own site
www.glamorise.com had the best choice so I searched the styles I liked in the UK. Their site has a link to their YouTube videos which is good. It explains the front fastening clasp that some people can't get the hang of. There was no internet when I started buying but it seemed easy and natural to me to open and close it. They also have videos showing the different types of bras, too.
Some people have commented that they worry how strong the ff clasp is. I've had some of these bras for over a decade. They've been in the wash sometimes twice a week and I have never had a wire break or poke out and the clasps are still working fine. I've not worn them constantly due to my size going up and down, but unlike many other bras, I can put them in my drawer for a few months and when I go back to them, the elastic hasn't degraded. I never tumble any of my bras, though, but having said that, some other brands still have baggy elastics after a few months.
I do use the VV type bras sometimes. I have a massive cyst in one breast that aches like... I'll wear one of these to bed or around the house when it's playing up. The best I've found so far have been the M&S two-packs. I double up if I'm really aching. I can get into a XL (I'm 38F), but I'm not sure if they'd fit very large busts. Other brands do bigger sizes, though.
