I agree with pretty much everything.
Children should be dressed in a manner that allows them to fully participate in the world around them. There was an online thing about girls school shoes v boys school shoes a while ago - since then I have bought my daughter (6) school shoes exclusively from the boys section, because they allow her to participate in a wider range of playground activities. They give her more options.
Context is useful - crop top good at dance class or on a beach etc. Not in the snow/at a funeral.
I try not to meddle in what my youngest daughter picks out for weekend wear - they spend 5 days a week in uniform so if she wants to wear bonkers combinations of stuff on the other days I let her.
Sometimes I have to actively stop myself from telling her that things don’t go together - much as I’d love to dress her totally to my own taste, she’s a human being, not a doll. I think it’s important to let her have that control over her physical self now, to not undermine her sense of autonomy and to reinforce the message that her body is her own.
Middle daughter is my bonus (step) baby, so she comes with a set of rules designated by her birth mother and while I think a lot of them are pointless (she’s not allowed to look at the boys section, for example) I try to walk a line that respects her autonomy without undermining her mum.
When her dad and I got married, she couldn’t find anything she wanted to wear in a shop. She ended up picking out one of my dresses and I had it professionally altered to fit her.
Little daughter insisted on a ridiculous mother-of-the-bride style hat with ostrich feathers. They don’t come sized for preschoolers so I had to make her one.
Re: sexualisation, well, having once been a phone sex chat line operator (late 90s, before the internet caused a ‘video killed the radio star’ type takeover) I can state with certainty that anything can be sexualised - from Velcro sandals to bursting balloons.
There is a touring exhibit in the US showing outfits women were wearing when they were sexually assaulted. It makes Sardine’s point very starkly.
We should try not to get bogged down in worrying about what signals we send to men via clothing - they don’t receive our messages anyway, they just write their own agenda over the top.
Fashion/clothing experimentation can be a wonderful thing, my mother was incredibly supportive and indulgent of my ridiculous sartorial imagination, enabling ridiculous fancy dress costumes (often made out of boxes) in my early years, and making stuff not had in my head but couldn’t actually find for my teenage nights out. Sometimes at ridiculously short notice.
When my daughter was born I made the conscientious effort to learn to use a sewing machine and dressmaker clothes from simple patterns so I would be able facilitate her future flights of fancy. I wish I’d asked my mum to teach me while she was still around to do so, but instead I remember her whenever I sit down and thread the machine. Fashion, style, what we wear and how we source it doesn’t necessarily have to involve men. I hope!
