I don’t think that style was popular 10 years ago- but covid warps a lot!!! The summer before covid was the first time I was seeing a lot of floral midi dresses with denim jackets and white trainers. It wasn’t ubiquitous though, until the summer of covid when that floral midi, denim jacket and trainer combo was the look of every mum at the park (with Prosecco on separate picnic blankets at least 2 metres apart as that was our social life)
I had hoped the midi length sun dress would be done by now - as a short person, its really not a good length, I can do knee length, shorter (so long as still closer to knee than arse) or maxi length. Cutting across the lower leg like that is not a good look unless you are very tall.
sadly, it looks like we’ve got another year of the shops that do good quality clothes aimed at middle aged women making spring/summer dresses only flatter tall ones.
