Who would wear them? Older teenagers pushing boundaries or girls on a night out.
100 years ago noone would have worn a bikini for modesty.
So I vote for less pearl clutching. Yes, it might not be to mumsnet tastes most of us arent of the young generation and probably wore some right shit when we were so let's just be glad we live in a society where women can choose to buy and wear. There are bigger feminism fish to fry.
