Lingerie laundry - handwashing: really??

[PacificDogwood]

After decades many years of living with M+S scanties in varying shades of grey, I am now the proud owner of 2 decent bras. With matching knickers, no less!
The bras were not cheap, but are not couture either (Bravissimo). No silk, just good old polyester and stretchiness.

So, do I have to handwash them? Or will a lingerie net in the washing machine on a gentle cycle do?

I just cannot stomach the thought of handwashing undies, particularly knickers, yeuch!

I have relatively nice underwear (mid range, not cheap but not the most expensive) and I bung them in the washing machine. The wire seems to pop out of it's casing after about 8/9 months but I think you are supposed to buy new bras fairly regularly anyway if you lose/gain weight as they then won't fit properly.

I try to avoid handwashing and so far didn't have too many desasters.
underwire bras I put in a pillowcase with zip to avoid expensive washing mashine repairs.

I always wash my undies in the washing machine. I am meticulous about separating colours though, and my whites stay white. My bras never come to grief in the washer either. Why would they?

Thank you, all .

Every label in my new undies says 'handwashing only'.

Bunbaker, apparently the underwires can work free. And destroy the washing machine, hence pillow case (good tip, thanks!) or lingerie bag
