I rarely wear matching sets of knickers and bras. A couple of reasons:
- I don't usually like the knickers that match the bras I like (I'm a 32G so it's already hard to find suitable bras that I like)
- I like my knickers to be comfortable and invisible under clothes (no VPL thank you very much) and those that come with my bras usually aren't.
However as most of my bras are black I usually just pair them with plain black knickers, which did not come as a set with the bra.
I don't think I'm unusual to not wear matching bra & knickers sets every day. So AIBU to think the majority of women do not wear matching bra & knickers sets on a daily basis?
