If you do a search for Her Universe, you will see there are some great shirts, skirts, and dresses in girls, misses, and women sizes. They are sold from Her Universe, Hot Topic, and other retail and online outlets.
The products came about when Ashley Eckstein who played Ahsoka Tano in the Clone Wars was unable to find clothes for herself to wear. She began Her Universe.
A word of caution on Her Universe products.....when she first started they were high quality, but she has definitely moved to a lower quality in the last two years or so.....very thin fabric, tears easily, and no warranty on faulty products. My daughter saved her money and bought a shirt....we got it in the mail and it had a pull in the fabric....asked for a return authorization to exchange it and was told sorry, it was fine when we shipped it.....ummm, so the post office kept the box is good shape but ripped the fabric inside? $35 for a shirt she can't wear.
Search and read reviews (that aren't on her blog/website) and you'll see we aren't the only ones with complaints about both quality and customer service.
Hot Topic on the other hand is nice quality and great customer service!
