Personally for my prom id go with normal eyes so like shades of brown which are really flattering for blue eyes.
And yes black mascara... i dont like blue mascara it can look tacky and this is your prom so you wanna look glamourous
Cobalt blue dress sounds v nice and quite bright so id keep the eyes toned down but still beauutiful
Just wondering whether you think its best to have blue eye makeup (blue eyeshadow etc) or normal black mascara etc. -- to match my colbalt blue prom dress?
It's either a wow factor for the lips or eyes, personally I would keep your eyes neutral with soft beiges and browns with just a little black eyeliner and some volume mascara and get a nice lip gloss/lipstick instead ;yes;
