I remember when I cut my hair all in one go (from waist to ear length) in December 2017, I found it suddenly easier to look 'trendy' if that makes sense? As in, outfits I would usually have to add colour/ texture/ accessories etc to would suddenly look like a 'look' as is - less effort was needed. I never went 'minimalist' but a bit more pared down.
The flip side was having to make sure everything was well fitted, since more of me was visible (no more hiding behind long hair, literally!) Necklines also had to be more comfortable (no more scratchy coat collars).
The other thing, which I think may affect you too, is that much of the jewellery I used to wear suddenly looked too 'heavy' without the hair to ground it. I'd often wear shiny earrings, for example, because they would be more visible under my hair - I found I preferred more matte earrings instead with short hair (think oiled bronze VS shiny gold).
Personally I did also find myself wearing more makeup then, just because I didn't like how the visual focus was now on my nose (partially the reason why I haven't gone short again). If I do though, think the shortest I would go is shoulder length, just to keep some contrast around my face. Don't know if you also feel the same way? I got it trimmed in June but I'm probably overdue for a 'proper' cut though, due to swimming taking its toll on my hair now too!
PS - I think I showed pictures of the side of my cut here on the forum without showing my face (fringe in front) Up to you, of course!
