In Minneapolis, Hailey & Chelsea want to host a party for their soon-to-wed older sister, Heather. And they concocted a unique theme: it's an ode to all the really bad bridesmaid dresses that every girl has ever worn. The sisters and guests even plan to wear real bridesmaid dresses to the event. So Robin is to make a cake that will replicate three of the brightly colored yet hideous dresses that will be worn to the party. White chocolate molded bodices are made to drape the fondant dresses on. High heel shoes are sculpted. An edible bridal bouquet is crafted, but time is running out... Christopher at Christopher Garren's Cakes meets Sarah and Brian, a down-to-earth couple who want a wedding cake that's not formal or fussy. Chris gets his design inspiration from their wedding invitation, which features a fun picnic theme. Chris and his team will create picnic tablecloths out of fondant to drape from the cake layers, and watermelon slices, dragonflies and dandelions will complete his vision. Chris wants to make sure that Kristen creates watermelon slices that appear very real. He asks his newest intern, Junior, to find three unique watermelons to use as references. But accident-prone Junior brings only two melons back to the bakery -- what happened to the third? Kate & Anthony ask Cleveland's White Flower Cake Shoppe to create a wedding cake with a winter theme. Considering there's plenty of snow on the ground, co-owner Lauren agrees this seems appropriate. The bride insists that the ivory-colored cake must be elegant, with only a hint of sparkle. Lauren's design incorporates snowflakes in all tiers, and some even dangling off the cake. Marianne is dumbfounded. How are they going to hang the dangling snowflakes? Adding to this the dilemma, how does one judge what is "too much" sparkle? In the end, they create a tall, elegant cake with twinkles of rock sugar and dangling snowflakes, truly completing the winter wonderland wedding theme.
