This is a very circular argument on S & B.
First, why come on S & B if you are not interested in what's stylish or beautiful? Or fashionable? Or interesting? Discussing trends is pretty standard stuff for a style board.
Second, the only reason usually people make these proclamations is that someone comes on and says I feel a bit unstylish or frumpy, I caught sight of myself in the reflection of a store window, what can I do? Then people try to help by suggesting things that are more fashion-forward, not things that are standard but have been around a while and probably going out shortly. I wouldn't suggest to someone they invest in Breton tops, but I think it's fine to wear them, especially if you already have them!
As for the floral dress thing, I honestly didn't know it was such a look, sure I've seen a few people out with this look but I don't have one floral dress at all, and never have done! I prefer separates, easier to style, I have a big tummy and they hide them and it's easier to mix and match.
People are wedded to their looks, in some ways that's eco-friendly to just keep wearing the same look, don't need to invest in much new to wear it, keep it going for years, I've worn some items for over a decade.
It is nice to have a refresh though, every now and again. Not if you don't want to and you like your 'look' but if you do think, I've been wearing this for ages, everyone else is wearing it too, I don't think it should be taboo to suggest that perhaps trying something a bit different might look fresher.
