I've never formally had my colours "done". I think I always had a fairly good sense of colour, but learning about colour theory at art college helped me properly understand things like hue, saturation, tone etc & how colours work together.
It's a fascinating subject, rooted in science, & I use it to inform my planting design palettes, as well as it influencing (but absolutely NOT ruling!) what I wear.
What I've since read about colour analysis (re clothes & make-up) sounds pretty sensible to me, & accords with the principles of colour theory. I probably do innately follow what an analysis would, I think, tell me - that I'm a soft autumn with an overlap with warm spring.
I had no idea that consultations often cobble it together with the Kibbe system (& didn't even know what that was until a couple of months ago). And having now read up on the Kibbe system of body-type - what an utter load of sexist tripe!!! And someone who dresses himself & his partner to look like this, will not be someone who influences me!
So, OP - I'd suggest you ignore the Kibbe part & sew the dresses you love!! But maybe take on board the colour analysis - whether some or all of it, depending on how much you agree with the recommendations??
