Update: Kate's Zimmermann dress is officially available online -- for now! If you're as obsessed as we are, shop it here.

When you're checking Twitter while out to dinner with friends and audibly GASP at the sight of a blurry, terrible quality photo of a dress (guilty), you know it's going to be good. And then when you see the high quality pictures and just about die (guilty), it's time to start saving your green... or find a look for less!
Naomi Watts in Zimmermann dressModeled by Naomi Watts for the summer collection, Kate Middleton's stunning white eyelet dress by Australian designer Zimmermann isn't slated to hit stores until June -- but fear not. On one hand, the design house is apparently scrambling to move up the release date (yay!) and on the other hand, you can get the look right now - and for a lot less money (double yay!).

Click through the gallery above to see our picks for similar eyelet dresses to wear all spring and summer long.

And if you just have to have the original, it will retail for around $520. Hopefully it won't sell out in minutes like Kate's DVF dress did...
