So, I'm just gonna go ahead and admit the unadmittable: I have been wearing some running bras for about 7 years now.
Dudes probably don't know that's a "bad" thing, but ladies probably know that supposedly, you're supposed to switch out regular bras once every 6 months or so (does anyone truly do this? I don't know about you, but last I checked, bras aren't cheap, so I know I don't replace bras that frequently), and because running bras are meant for the nitty-gritty of ta-ta support, you're not supposed to wear one for even that long.
Sports bras are just as expensive, if not more so, than regular bras, so who truly can afford to replace them that often? And, what do you do with the old ones? You can not donate bras, no charity accepts them, because, um, who wears someone else's old bras? Especially running ones that have months or years' worth of sweat saturation? Yummers.
Anyhoo, as I said above, I have a few running bras, which I'll be honest, are very comfortable, and I've been wearing them for far too long.
And, unfortunately, boobs change after you have kids. Sorry, if you don't have kids and you want them and think that your boobs now will be the same afterwards; I'm here to burst that bubble: Kids will ruin your boobs. During pregnancy, you get totally rad boobs, and then if you breastfeed, the radness continues, but then when you stop nursing? Nature is like, "No boobs for you!" And then what you're left with is something that resembles an orange in a tube sock.
In short, my boobs now are not what they were years ago when I first started wearing a few of these old bras, so the truth is, even though those ancient bras are comfortable, they're not really giving me the support I'm supposed to have while running.
Knowing this, and being concerned for the support of my sweater bunnies, Jerry bought me some new sports bras as an anniversary gift (forget Victoria's Secret, I want Nike!). The past few days I've been able to wear my new gear, and I have to say, they are delightfully comfortable and, wow, HELLO support!
Guess I need to demote a few of the really old bras.
Ladies, what's the longest you've worn a sports bra? Dudes, aren't you glad you don't have to even think about this?
