I love, love, love the fuchsia! It's just enough of a pop of color to give your outfit a fun, summery feel. Personally I would also wear some chunky chain gold accessories like these: link to complete the outfit. Even if you think that's too much or too tacky for you, you should at least try some finer gold accessories with the outfit! In fact, I'm loving that combination so much I might just wear that out myself tomorrow!
the black looks best color wise because the dress is bright enough on its own but the flaps seem too much w just a straight clean dress but they still look best of the 3. the fuchsia w bright teal looks very 80s neon glowing and they take attention from your dress. just not a fan of the yellow.
