Ok. I was trying to work out if you're more a brunette with summer/ winter colouring in which case I'd suggest soft pinks and or greys. But as you have blond/caramel and your dress has gold, then beiges and browns would be better. (these are more spring/autumn colours in the old colour my face palatte thing)

Blue and yellow are complementary colours, so goldish eyeshadow will work well. Use a brown or brown/black eyeliner and same colour for mascara (try a waterproof one).

Use a light colour on your lower part of your upper lid. On your upper part use a slightly more bronzed colour. Use a darker colour along the ridge that separates the upper and lower parts (outside only). You can also smudge the darker colour along the eyeliner or on it's own on the lower lid below your eye. It really depends on the shape of your eyes. Play around with it.

Sometimes the lightest colour looks best on the upper lid and yhe middle colour on the lower lid. Dont pluck your eyebrows too thin. Too thin eyebrows age the face and give a surprised look.
Thanks Tashybabe - will have to play around with my eye shadow and what i have in the cupboard at the moment. Normally i wear a dark grey color which brings my eyes out alot, but considering this is my Wedding day I dont wanna look like Im going to work - but I dont wanna look like a drag queen either! Will take some pics of my eyes too just to see how they look in pics!

Thanks Everyone for the responses!
