Hand wash. If using machine, put into lingerie net/bag.

My lingerie last pretty much at least 7-8 years.

My clothes last that long too haha. Most of the time it's still in wearable condition when I give them away.

Giveaway to maids or charity. Most of the maids that I gave to, all like very happy to receive it. Since it's still in wearable condition. So far haven't come across a bra that's not in wearable condition lol. I guess I'll just throw it out or put into those charity bins.

Some times the bra companies will have promos that if you bring in your old bra, they will give you some coupons/vouchers/cash back in return.

Wah 1 year? That's very fast!
How often do you wear the same bra? Maybe cause I have tons of them also lol. So it doesn't wear out so quickly. None of my bras had wires poking out before. Mostly is the elastic band at the back will go out of shape and looks like it lost it's elasticity.
