Have you ever wondered what the lifespan of your underwear is? We're pretty confident that it's a lot less than you think it is.
In fact, when was the last time you found a hole in your socks but wore them anyway? Or felt your bra become a little bigger but ignored the fit?
There are some things that we just don't think we ever need to replace unless we change size. A bra is for life, right?
Well, maybe not! According to experts at BlueGuard, the folks who've invented a pair of socks they promise will last forever, we should be replacing our bras every SIX to EIGHT months.
They said: "Washing machines cause the padding in bras to lose their shape, and for those who wear the same bra frequently, the elastic won't last much longer than half a year before it starts to become slack and unsupportive. Make bras last longer by rotating them, and washing them in cold water, which can help elastic recover."
Equally, your panties should be replaced every six months, while they recommend that socks are thrown away after a year.
If that doesn't make you want to go home and cleanse your underwear drawer, we don't know what will.
