If you're looking to find good casual clothing for your kids, nieces or nephews, you should definitely take a look at Lilliput's collection. They've got great denim jackets, plain and printed tees, and super cute apparel like denim over-alls as well. Lilliput retails apparel for kids between the ages of 2 -7 years old.
They've got good cargo shorts, pants and denim skirts, too. Also, you can find decent footwear for your children at their stores (although, that's not what they're best known for).
