Only when they either get really sweaty or start to smell. I only have two bras, and I'm always missing one of them and wearing the other one.

I'm an at home mom so 80% of the time I'm not wearing one. I really don't have to wash them often

when they r dirty

I was them whenever I do laundry and wash my jeans. About once a week or once every two weeks or so. I always hang them up after each use anyways.

I used to wash them after every wear, because that's what my mom always did, but she wears a lot of soft cup bras, and mine with underwires were getting DESTROYED. Now I only wash them after a few uses, usually when they start to smell sweaty

when they seem dirty or stretched out

Whenever they seem dirty, really. They pick up scents less than other things which is nice..

I throw them in with the rest of my laundry, whenever that piles up.

Oh thank god I'm not gross!!! I used to worry people would think I was crazy because I wash them like once a week tops, I hate washing them because I only have a few I really like

It depends. I like them clean. Y'know, boobsweat. I hate when the straps get discolored, so I wash them pretty frequently. I never wait until they smell. Usually every 1 to 3 wearings. (And I usually take my bra off in the evening, if we aren't going out. I just do that thing where you pull it through your sleeve, after unhooking it. My husband used to think it was a magic trick. He hates when I forget and leave them on the couch. Or on the stairs. )

I nearly always wash them in the sink and then roll them in a towel, let it sit for a while, then hang them on a drying rack.

Once in a while, I put them in a lingerie bag and wash them on Delicate. But, I NEVER put them in the dryer. It destroys your bras. Mine have underwires and some lace and some have pads on the sides to push things in and the dryer destroys your elastic. I prefer my bras last, as I try to buy nice ones and I don't want to have to replace them too often.

I don't wash them as much as I should. I wait until they're dirty.

Every few days depending on how bad I have sweated

I wash them once a week when I do the rest of my laundry, but I rotate between them so it's not the same one that I'm wearing every week.

I prefer to wash mine after every use. I like mine feeling so fresh and so clean.

I wash them after ever use....and now I feel kinda weird lol

I don't sweat, to a point where it's a problem with thermoregulation and all, so... I wash them when they smell like something...

I wash them every time i put them in the dirty clothes bin. ^_^ Can't have a stinky bra!

Typically every week, or whenever they seem dirty.

Every two or three wearings.

I usually go through 2-3 bras in a 2 week period. I wash clothes whenever my laundry bag gets full and that's about a week and half to 2 weeks usually (trust me I have enough clothes to go that long without doing laundry) lol

whenever

I don't wash them too often. I always hand wash them since they are delicate. I have around 6 bras I rotate so I probably only wash them every month or so.
