How often do you buy lingerie (girls), do you make do or replace when money is tight?

I have a needlework set and I know how to knit lace, so I can repair my underwear when it’s necessary, but some are getting to be unsalvagable and need to be consigned to the rubbish bin!

I’m used to fairly expensive lingerie and I am very much looking at replacing it with basic styles to ensure it lasts. Not a happy venture. I’m still hand washing my very delicate pieces as the washing machine here is old and a little savage!

I’m hoping my parents will send lingerie as my birthday present next month, as I have asked them to!
