The E! reality stars -- together with two of their "Dash Dolls" employees -- are covered with airbrushed bodysuits that say "Dash Miami."

"Kourt and I came to Miami to revamp Dash, and that's exactly what we did!" blogged Khloe, 25. "We worked our little tushies off and were so excited about the store's fab new makeover that we thought what better way to celebrate than by getting one of our own. Dash has never looked so good! LOL."
