I'm planning on wearing blue flip flops tomorrow but my nails are red. is that ok?

yehh!
it really dosent matter!

Yes, my 13 year old daughter very into fashion and she says that its perfectly ok.....

I think it's cute when some accessories match like earings and purses maybe even your eye shadow, nail polish can be a nifty tool to bring out the colors you are wearing. It doesn't have to match though.

Red nails with blue flip flops are a bit opposite.. unless you are trying to patriotic! (If you live in the U.S.)

It's not that big of a deal if they don't match soo I say - Yes. It is okay!

i hink so because if you wore blue shoes,blue shirt, blue shorts or pants, and your nails wer blue, that would look really cheesy
