Technologies are presented that provide contextually interactive apparel in practical implementations and applications. A method for directing a change in an interface of a wearable device may include detecting a trigger and providing a change command to an interface controller of a wearable device based on the trigger. The interface controller may direct a change (e.g., a change in visual pattern, audio, etc.) in an interface of the wearable device, based on the change command, that is perceivable by persons in proximity of the wearable device. The providing the change command may include providing one or more change commands to a plurality of wearable devices in a choreographed manner. The method may further include determining other wearable devices that exist and/or are being concurrently worn within a predetermined proximity of the wearable device, and providing information regarding the other wearable devices.
