Ok. This may not actually be true for you. Everyone has different bodies and different experiences. But as a person with 3.25lbs (each) boobs, it's been a little life changing switching to corsets daily instead of bras.
You don't know how much I love lingerie and bras, so let me start there. I own dozens of beautiful bras that range from a couple hundred each to about 30. I've been professionally fitted multiple times, as well as fitting myself. I was wearing high end super supportive bras in my proper size, and I thought that was as good as it got. I mean, it was infinitely better than going without.
How, you ask, did I discover that a good overbust corset is boobie magic? Sadly, by tragedy, with a not so fun injury. I have EDS (Ehler-Danlos Syndrome), which in layman's terms, means I'm held together with stretched out rubber bands. There's more to it than that, but that's the important part for this story. Well. I dislocated my sternum. I got a dress caught over my chest and couldn't get it off, hit the bottom of my breath, tried to breathe in, and the wind was knocked out of me instead. Taking my sternum, collarbones, and ribs with. I tore the cartilage attaching most of my ribs. It was possibly one of the most painful things I've ever gone through. Not just because of then, but that the pain pretty much didn't stop for a month. And only then did it start giving me occasional days off.
Anyways, after I realized what had happened, and had my bones put back where they were supposed to be, my doctor recommended I wear one of my corsets 24/7 as a brace for my ribs, until they healed back how they were supposed to be. She told me to put moderate pressure on my ribs, but to be careful not to put any pressure on my sternum. So my beloved bras were out. But I couldn't leave my boobs all loose and willy nilly either, since they pulled on my ribs and it hurt massively. I could get away with an underbust and no bra only if I lay very still. So I started wearing an overbust corset. It held my boobs in place without pushing them into my sternum, applied pressure to my ribs, and genuinely felt awesome for relieving the pain.
As I started to wear it more, I realized a couple weird things. I didn't have a hot spot on my back between my shoulder blades anymore. My neck started hurting less. My shoulders weren't straining against straps. And finally, the permanent line where the band hit began to disappear. I felt like I wasn't even carrying the weight of my chest anymore, since they were being supported from underneath.
Seriously, it's like walking around with someone else carrying your boobs for you. (Magic)
I don't think I can ever go back. I'll still wear bras for photoshoots with underbust corsets, but may never be anything more permanent than that. It's kinda like wearing crappy shoes all through your early twenties and then discovering that Clarks exist. I'll miss all my beautiful pieces, but it's hard to miss the back, shoulder, and neck pain. Not to mention the deep painful marks they could leave, or the permanent shaping.
So tell me, fellow heavy boob havers, what do you think? Would you try it out?
