My sister bought me a menstrual cup a few years ago. Never used it. I'm sure they're great but not for me.
My MIL bought me the pants I always wear for xmas last year. They're all lace thongs from Victoria's Secret and they're pretty skimpy. I thought it was a wee bit weird tooOne year at Christmas from the inlaws I got this really nice looking cardigan, then when I looked at it closely it was a maternity one. I wasn't pregnant. She also bought me knickers another year, we'd been living with them inbetween house moves so presumably she'd seen mine weren't in the best condition but no DIL wants their MIL to pick out their pants for them! They were all high leg ones too which I never wear (but she does)...had a lovely conversation with the woman on the refunds desk at M&S about it
