Teri-Lu wore a blue dress that had two triangular stripes on it, similar to the badges worn by the crew members on Star Trek. She was also typically seen wearing headphones with a microphone attachment, doubtless for the purpose of answering phones. She also wore a white arm band around her white elbow; in the Knuckles Archives she also gains white gloves. Teri-Lu had blue eyes in both incarnations; in the original Knuckles comics she had red fur, but the Archives recolored her to give her yellow fur.
