I think you & I may have similar undertones to our skin, so I find stripes can wash me out too. That said, my hair is still (mostly ) black, so I decided to keep this stripe top in the end because the autumnal colours add enough depth to border on more flattering than usual (the background is cream rather than stark white, which is usually hard to find in striped tops):

Kettlewell (the brand of my top) sell clothing according to your seasonal colouring, so just thought it may be a good resource if you're ever looking for something similar.
On reflection though, I think the thinner & further apart stripes in your tops are much more flattering - it's likely why I felt a bit like a 'giant toddler' in my version. I don't regret it though since I still wear this top, but just with a scarf or topper to break up the pattern. I've found the typical navy & white Breton stripes too unflattering though

That said, I'm glad you attached that photo of yourself in the dark floral print, because it's lovely on you! I think side-by-side comparisons can be really useful, because although the stripes look 'OK' on you, the softer rounded pattern is much more harmonious with your overall look! So I'm attaching photos of me doing the same thing:

I think seeing those photos together makes the difference in traditional figure flattery all the more stark. It may have something to do with Kibbe types (I also struggle with classifying my face as not being angular but not being completely rounded or soft either) but I'm unfortunately not much help with that because I don't even know my own Kibbe type But it could be a good starting point for further analysis on why certain patterns work better on you (& me) than others?
