Clone Zone - How to work an ivory silk dress like Suri and JCrew crewcuts

Loving little Suri's ivory silk dress that she wore this week in Melbourne while out and about with her superstar mummy & daddy, Katie Holmes & Tom Cruise. I haven't yet established the origin of this particular dress but found some similar dresses from JCrew crewcuts, a fave label of First Lady Michelle Obama. From left to right above we have the following:

1. crewcuts Girls Slub Cotton Silk Ruffle Dress in Pebble
2. crewcuts Girls Solid Cotton Ruffle Dress in White (love the Bronzed Twig colourway even more!)
3. crewcuts Girls Tiered Silk Taffeta Cody Dress in Ivory

Any ideas on the origins of this dress would be greatly appreciated : )

UPDATE: Thanks to info on Stardust's blog, the dress Suri is wearing is from the upcoming summer collection from Aussie kids designer label Tiddles & Chinch. A cotton version is available through the Ten Little Indians online boutique. I must admit, I have not come across this label before - they have been around since March 2008 and are based in South Australia but I recommend you check out their website - they have some really cute separates and I particularly love their peacoats.
