Laurie, we understand what you mean about living in a patriarchal society. Firstly the same patriarchy that influences what you see as 'sexualised' fashion also gives us 'office dress codes' and 'appropriate workwear' - which is also either sexualised in it's own way, restricts movement, is usually more expensive and less practical than most male office wear. Pencil skirts, skirt suits, court shoes, dresses, accessories, handbags, dry cleaning bills, slacks which need ironing... and so on.
A fitted lycra dress is machine washable, doesn't need ironing, is easy to move in and non-restrictive.
Secondly, we all live in a patriarchal society which puts enormous pressure on us - we have limits to the clothes we can buy, where from. how much they cost, how practical they are, how many purposes they serve. Plus we are all human. We are all affected by this and being a feminist doesn't make you exempt from those pressures. So stop telling other women what they should and shouldn't wear. Is it kind or helpful? No. Its just another way of blaming women.
