Well, I love the white the best, but that's because that's what looks best on me. It goes with everything, though tends to be more "dressed up" than either the pink or lavender. The great thing about the colored strands is that you can dress them up or down. They'd look great with jeans, but you could also wear them to work or out to dinner.
I had something like 3 different lavender strands sent to me from PP, and I ended up returning each one because I couldn't find one that looked good with my particular skin tone. I tried lavender that leaned towards pink and one strand that leaned towards bronze. I ended up concluding that, while I love the look of the lavender, it's just not for me.
