I've been reading S&B more often these days, trying to get my head around the angst that so many women seem to feel about clothes flattering the figure, looking neat (or not scruffy), and terror of spare fabric floating around.
I've come to the tentative conclusion that it's an internalised directive to look slim and, if one is not slim, as not-large as possible. Not only is this unnecessary, it's directly opposed to the way fashion's going at the moment - unless you favour the skin-tight, barely-there aesthetic. That's going nowhere, but then you wouldn't be reading 'jeans and a nice top' threads!
I'd wear anything @NatashaDancing and her fashion-forward pals post, if I could afford it and had somewhere to go. I'm tall and wide - not curvy wide, just rectangular. I'm also old, broke, and only go 'out out' once or twice a year. In real sizes, I'm a 20/22 but everything I've bought this year has been in sizes 12-16 (yes, this is getting ridiculous!)
So my oversized shirts are labelled 12-14. They're less oversized on me than a skinny 17-year-old would wear them, but work perfectly. They only touch my body on the shoulders. They move when I move, giving a sense of flow, and they're a bloody dream to wear.
Floppy sleeves aren't a problem: they look nice, there's a huge variety of styles to experiment with, and you'll find that most of them have a tab or similar apparatus to hold them back if you're doing the washing up or something.
I've got no issue with wide-leg trousers: yes, they make me look even more rectangular, but the point is that it doesn't matter. Skinny trousers make me look like a parsnip - in fact, they make everyone parsnip-shaped, except 6ft women with tiny hips! Wide legs have movement, are comfortable, and don't make you look as if you're afraid of taking up space.
You may have noticed that the coming silhouette is sort of trapezoid, with plenty of air between you and your clothing. One of the joys of 2020s fashion is that pretty much anything goes ... but things start to look dated anyway. And the longer you cling to a sense that you must be tightly clad, the sooner you will, I think, look old fashioned.
The beauty of all this is that you can just stick something loose over whatever you were wearing, and you've more or less solved it 😄
