I love this thread; it's awesome to read everyone's thinking process and their routines.
Oh good, rachylou, that means I'm not the one with the most bras I think if I counted the ones that are the wrong size now, I'd have over 15, and that's not counting any sports bras (4ish) or the couple strapless ones I only wear with formal wear (honestly, it's been years, I'm married, most of my friends are married or aren't gonna get married, there are probably no more bridesmaid dresses in my future, I should just donate them because god knows they aren't comfortable to wear).
As I'm replacing bras I've bought a few underwire pairs because they are so much easier to find. For years I've been anti-underwire because I don't think they're as comfortable but I'm resigning myself to it for now. We'll see how the washing process goes in a mesh bag on delicate because as I've written before I categorically refuse to do hand wash. (Want to be really shocked? Until I started wearing underwires I put my wireless bras through the regular wash cycle and the dryer, at least in the winter when I'm not line drying all my wash anyway.)
Harmonica, I think either fresh pair or bare necessities has a similar mesh thing that has an internal structure built in, like the one you posted. I imagine it could be really handy keeping foam cup bras from collapsing/being squashed in the wash.
