Stephanie Pratt and Lo Bosworth were dressed for a yacht party in smashing summer style!

Stephanie showed off her perfect bod in a horizontally striped, short-sleeved mini, which she paired with open-toed heels.

Lo Bosworth’s naval-inspired ensemble was oh-so-simple, but totally chic. The Hills alum wore a navy blue long sleeve t-shirt over white shorts, jazzing up the pairing with a blue Chanel flap bag and tan platform sandals.

We love Lo’s fancy footwear!

Samaire Armstrong looked foxy in floral, wearing a hautely hued mini with white accessories.

Simple white peep-toes finished off her look.

Christian Serratos flirted in fab summer style, wearing a white ruffled mini with sparkly sandals. We love how The Twilight Saga: Eclipse star added a color-popping blue clutch to the mix.

Charlotte Ross (on left) looked perky in polka dots, while Taryn Manning looked chic in a white Urban Behavior strapless.

Taryn kicked in black and grey cutout heels, which were super snaky!

Elizabeth Rohm score low points on the fashion front, looking like she was headed to a Christmas party in a red and black embellished dress.

Grommet heels graced Elizabeth’s feet.

We love how Maria Menounos took advantage of color blocking, wearing a mellow yellow bandage mini with a simple black tank.

Golden Brooks looked smashing in startling style, rocking a thick leather and metallic belt over a crocheted mini.

Stacy Keibler looked beyond gorgeous in a one-shouldered alice + olivia frock, which featured a slender gold belt.

Ashley Scott kept it simple in distressed denim and a grey tank.

Erin Lucas channeled the Material Girl, wearing a clever City smart ensemble, which featured a coned bustier!

Brooke Mueller seemed to be rehabilitated from the stressful events of the past few months, but Charlie’s ex should think about adding a stylist to the payroll. Dressed in unflattering black and white duds and black satin boots, her look was better suited for a winter event.
