A while ago I read that Mariella Frostrup's secret to non-sagging breasts is to wear a bra all the time, even in bed (apparently this was recommended to her by the late Paula Yates). I know from experience that it's not comfortable wearing an underwired bra to bed and I have long been keeping an eye out for a comfortable but supportive sleep bra. This search has proved very difficult as most shops do not stock H/HH/J cups as standard.
As you'll know if you've read my previous posts, I recently placed a large lingerie order with Fashion World in the hope that I could find bras for various purposes; one of which being a sleep bra. Unfortunately most of the bras in the region of my cup size were only available in a 38 back, which I did order but quickly discounted after trying on one (review below).
