Have you looked into the Ethereal style persona? It's kind of building on Kibbe, but the idea is that it's using the more pastel colours (that suit you) in a more dramatically mysterious way. You don't have to go for that exact way of dressing, but just wanted to throw it out there in case it helps - maybe try a small pastel item near your face (like a scarf)?
There's a Kibbe saying that clothes don't have an ID (type), but rather the overall outfit does - I've seen items like a cream pussybow blouse under a satin lapel tuxedo blazer (both romantic) but with sharp shoulder pads, ripped black jeans & fingerless gloves (romantic edge = slightly more gothic). So it is possible to juxtapose styles!
I also 'suffer' (lol) from a juxtaposition in my natural body type VS colouring, so I do sympathise - i.e. I suspect my Kibbe type is either Romantic or Soft Classic, but my seasonal subtype is Deep Autumn. In other words, I can't do the softer shades of a 'typical' Romantic unless I want to look like an pastel zombie, lol. My compromise has been wearing darker colours but with more 'pared back' versions of soft silhouettes (like slightly rounded boatnecks instead of a deeply scooped neckline, or bishop sleeves but without any shoulder gathers/ puffs).
I'm nowhere near being a fashion icon lol, but I think this balance helps me to convey my personality (not too 'innocent' but not edgy either). Feel free to disagree though, haha!
