I created identical twins, Lilly and Daisy Ashton. They're two sweet girls, who look and dress exactly alike, but have different personalitys. Although both of them have nice personalitys, I didn't want to make the old cliche of one good twin, one evil...eh.
Here's the link to the two of them....http://www.thesims3.com/assetDetail.html?assetId=555314#
And here's the link to just Daisy, I thought I'd upload just one of them so you could see what their different outfits were.http://www.thesims3.com/assetDetail.html?assetId=555316
