Jeremy is a handsome young man, standing at 6' foot tall, he has a well-built form and possesses dark brown hair and eyes to match. In the first two seasons, Jeremy could be considered "cute" with a lean body, however as seen in the fourth season, his body is much more defined and muscular.
Jeremy's style over the seasons has changed somewhat. During Season One, due to the loss of his parents and his drug addiction, he usually was seen wearing black clothing, hoodies and dark jeans. Post-Season One, his clothing style became much more relaxed, seen wearing lighter colored clothing and wearing a tux for special occasions. His dark hair was originally short, slightly spiked which grew into long bangs, however in the later two seasons, it has returned to it's original short brown cut.
When Jeremy became a member of The Brotherhood of the Five he became much more active and gained a substantial amount of muscle.
