For Rosie's dresses I usually use
Prissypawfashions.com. Cynthia does a fantastic job! I have been pleased with every dress I have purchased from her.
I recently bought from
FairyTailsFashion.com also. I was pleased with that too. And Yorkie Haven Rescue at
http://www.yorkiehavenrescue.com/boutique/home.php.
Good luck on finding your Easter dress!
