If the bra isn’t comfortable, you’re wearing the wrong bra. She looks like she’s the size that I am and, IMO, it’s all about choosing the right kind of bra and having it fitted to your body.
It’s quite possible to get a good and flattering bra in her size. That are not granny bras either. But you’d have to go to a proper lingerie shop and not H&M.
I can’t help but thinking that with her infinity of illnesses, surely a bra with proper support would be nice.
This is something I wish every woman knew. A bra is never supposed to be uncomfortable. Ever. If it is, you're wearing the wrong size. Or the wrong shape.
And you're absolutely right that it is possible to find a nice and flattering bra in her size. You'd think with all the money MM is willing to spend on expensive designer outfits she'd invest in some proper support underneath too, but somehow I don't think it's a high priority to her.
It would be good to have yourself measered once in a while. Sometimes you end up with surprises, as I did. According to the measurements I had once I ended up with one size cup bigger then I thought I was. Also so old bras were thrown aways as they started hurting (the wires).
But personally I am not a fan of clothing shopping, especially when it comes to bra shopping. So I have to kick myself once in a while for it.
