Item: Senator Amidala cards
Set: Star Wars Clone Wars Adventures

From Amazon.com: Topps introduces the ALL NEW Star Wars: Clone War Adventures Trading Card Game. Based on a television show, Clone Wars is the #1 show with Boys ages 6-11. This easy-to-play kid friendly card game complements the HOT NEW online game from Sony! In total, 140 cards feature Star Wars characters, ships & vehicles. Additionally, there is a code card in every pack for the online virtual rewards!
The outfit on card 7 is similar to one she wore in Attack of the Clones; while card 55 has an all-new outfit. Unfortunately, this was the last set that Topps produced based on The Clone Wars.
I purchased a starter deck and several packs of cards at Target in August 2011.
