make up for a special occasion

That outfit is gorgeous ^_^ .  Maybe you could use some purple-ish lipstick to go with it, and maybe some dramatic eyeliner.  Whatever you do, stay away from teal eye make-up, though, as matching your outfit that much might be a little weird.

Nice outfit :)

I'm indian as well, and these sorts of shindigs are always fun to pull out the makeup you never could use in real life, lol.

Have you considered metallics? With all that silver in the outfit, you could always pull out a nice silver shimmer. I don't think there's anything wrong with blue-ish shadow, per se, but i'd definitely keep it in a creme-based light shimmer area and not, say, a more opaque powder-based blue.

Play up the eyes and play down the lips is always my advice.  Sweeping the shadow across the lids and then putting some below (but close to) the lower lashes also looks nice. I'd honestly go more with a nude/natural lip color than purple, but that's probably because i think purple lipstick looks too harsh on me. It's hard for me to give you advice without knowing what you look like since the complexion matters just as much as the outfit. (in other words, take what I'm saying with a grain of salt :))

In general, though, us indian girls tend to make out well with almond shaped eyes that look very pretty with some dark liner, mascara, and shimmer. Also, if you have brown eyes, consider a purple shadow. Purple really makes brown eyes pop.

good luck!

I was thinking a pale gold-ish shimmer eyeshadow with smoky smudgy
liner around the eyes. Really emphasizing the eyes with a sort of middle-
eastern kohl-y look while downplaying the lips with a more natural nude/
pinkish glossy look. (All the beauty experts seem to say that you should
either go strong on the eyes or the lips, but not both at the same time.)

Pretty outfit there! You're going to be striking in those colors with your
coloring. Felicitations to you on your big day. = )
