My favourite silver/grey eyeshadow currently is an “Eye Def Glitter Shadow” by Hard Candy in the shade ‘liar’. You can buy it from stores such as Walmart. To quote the website : "Eye Def is a unique, crease-proof, stay put cream eyeshadow that delivers stunningly rich color payoff while maintaining a just-applied fresh look all day long. Designed with an oversized, elongated, angled, doe foot applicator for one easy swipe over lids. Available in gorgeous metallic shades and ultra fine glitter shades."
Hey! That sounds beautiful, and perhaps a lot like one of Lauren Conrad’s looks at a red carpet event? Take a look at THIS. I think it’d work nicely to match your eyeshadow with your dress, so like, a cream/metallic blend. The cream will really compliment your eye colour, and the added touch of metallic will mirror the sequins and be very suitable for the occasion. Any of these colours would look lovely.
