A kilt can be worn lower on the hips, but this depends on the style of the kilt and personal preference. Traditional kilts are designed to be worn at the natural waist, and wearing them lower can affect how they hang and move. However, many modern and utility kilts are often worn slightly lower, closer to where pants sit, for added comfort and a more casual feel. Lowering the position will change the overall appearance and where the kilt falls on the leg, so it should still maintain a balanced and proportional look.
