Wow! Congrats on the Diva!! I too, am a Orbea convert after the boyfriend bought one for me recently and had so much fun blinging the bike out, oh and riding her too of course.

The thing about doing up the Diva for me was definitely finding and matching the right shade of white (in your case purple). But to me, the frame is so blingy and flashy on its own so it needs very little added to it. If I had the purple/pink frame, I would look into small details like purple handlebar tape, purple cable housing, even things like purple valve caps to make the bike 'pop'. Everything else I'd stick to black/white, as things like purple saddlebags and bottle cages are extremely hard to find. The saddle that my Diva is sporting atm would be perfect on yours!

I really hope you'll enjoy riding her, and to be honest, even if you don't do anything to bling the bike, she'd still be a very flashy ride.

BTW: Here's a photo of my Diva, looking to buy a pair of white wheels eventually to finish her. I don't know how I'm supposed to balance out the hint of purple on the saddle with the rest of the bike but no one can see while I'm riding anyway.
