Blue or Black for a Fendi Peekaboo?

I have to agree with you, I like both of them. however, if it was me spending that much on a bag, I'd stick with the black because it goes with more things that I have. (also, when I go with something that isn't a neutral, I prefer loud & the blue is not quite loud enough for me.)

Although black is more versatile, I like the blue one better. If paired with a blue belt or shoes, you can also use it with any outfit. I think it's more trendy :)

Personally, I like blue.
