Why is a skirt considered pretty?
And why do we think wearing a strip of fabric over our legs that doesn't have two separate sections (trousers/jeans) mean we are more dressed up?
It is all a matter of perception.
You may be the type who doesn't really feel comfy in them day to day. Ir you might be holding yourself back when you'd love to incorporate them into your everyday wardrobe. Only you can fathom with this is.
I was like this for years. I loathed jeans and trousers, but wore them to death. It felt 'normal' and casual. Because the market has prioritised them as easy, whereas dresses and skirts found themselves resigned to the party bin.
I don't get this, personally, and don't see the issue. It's great that women have so many options (unlike men and whatever), but we do tend to bog them down with associations that are meaningless really.
You absolutely can walk a dog in a dress. The important thing is the coat and footwear. One could as easily snag on a bramble in wide trousers as much as a thick, winter appropriate dress. The fact that it is open throughout the leg makes no difference with the weather.
The issue is, as I see it, the market primarily creates coats that work well with jeans. The ubiquitous denim. and as hardy as denim is (that is what it became famous for), im always baffled as to how such a stiff and peculiar garment took over our priorities.
Good boots, a long pair and some ankle/doc style boots for winter go with most dresses. If you want to explore this, choose wonder dresses with more muted, seasonal colours and a heavier weight (preferably with the skirt lined). I see many women in rural areas powering about or dog walking in skirts and dresses all the time. Coats are a different matter though, and especially raincoats. Everyone says you shouldn't wear a dress that is longer than your coat but this is also complete bollox.
I have seen some awesome, casually dressed woman in dresses, boots and shorter rain macs. Just try to avoid lurid or overtly crazy patterns. I would also recommend natural fabrics, which are rare and expensive, so there's that to think about too.
