Both are nice, and both look great on you, but I think I'd go for the pink for daytime, and the white for a more formal setting. It just depends on where you're going. Both are great on you.
@aly_x3 The black bow limits you in accessories. I'd keep it simple, with only a bracelet and earrings. Black would be great, or diamonds for sparkle. Fakes are great, & would be believable with this outfit.
