Evan Kestenbaum, MBA, of Optix Family Eyecare Center in Plainview, NY, believes that a successful trunk show should feature a top-selling brand with name recognition. Display that brand in abundance and enlist a frames rep to help present it. Use social media to attract existing and new customers. Specials and a gift with purchase also drive sales. When the trunk show is over, he says, measure the success of the event--to help you plan for the next one.
