Do Muslims/Jews/Quakers etc use the term 'modest' to talk about how women dress or should dress, or do they not?
Rhiannon Quakers used to have a thing about "plain dress", eg not letting buttons show on clothing because buttons were frivolous. Quakers have moved on a bit since then.
I will put money on some Quakers dressing plainly because of the "simplicity" testimony of Quakerism, other Quakers dressing plainly because they can't be arsed not to, and yet other Quakers loving fashion and dressing accordingly. Same with Muslim women and Jewish women.
I don't care if any woman wants to cover up or strip off. I cover up, but not because of my faith. I cover up because I have bingo wings and cankles and do not wish to show them off to the populace. I do have friends and relative who cover up because of their faith, but that level of covering-up varies very, very widely. I also have friends and relatives of faith who get really, really pissed off with other people of faith being the ones to determine what is "modest" and what is not.
I've already talked about seeing a mum in the playground being bullied by other mums for her "immodesty" in showing her upper arms. I also have a much younger female relative who has a faith, and who considers herself perfectly modest, and yet who has had to stop shopping in her favourite shopping area when she's alone because she gets hassled by young men for her "immodesty" in not dressing like they think all women should dress.
And here we have a major high-street retailer, with a very particular view of what counts as "modest", pushing that view out as something mainstream and respectable. Their actions in selling these clothes is great - all women should be able to buy the clothes they want easily. Their actions in labelling these clothes as "modest" will contribute greatly to women - including women of faith - getting bullied. it's a disgrace.
