Trends seem to dictate that every single woman on earth right now wants a vast, floaty, tiered polyester monstrosity.
I have no idea where the middle ground is, if you want something warm, casual and decent. I have seen heavier weight dresses in stores like Toast, Plumo, Poetry, etc, but they are all extremely oversized. How I would styles a decent winter coat over any of them is a mystery I don't care to solve. And don't get me started on short fucking sleeves.
It is like there is this presumption that we only wear dresses to party.
I hate trousers, they don't suit me, and I am tired of the stiff experience of all types of jeans. I have found a dent weight midi skirt or shorter with a good knit works well in the mean time. If the weather is dire with gales and rain I would simply pop my leggings on with a longline cashmere jumper and raincoat over the top.
Good luck, I wish I could be of more assistance, but it has been this way for many years. Dresses are always subject to Uber-trendiness so rarely function well for day to day. It arses me off.
