Whether your closet is modest or extravagant, beautiful lighting can make you feel much more glamorous when getting ready for the day.  A chandelier can work in even the smallest of walk in closets, just make the proportion works so that it is not taking up valuable storage space towards the ceiling.  Go strictly traditional or wildly eccentric, this is a place where very few people will ever see your decor, so make sure that it is 100% geared towards your personal style.
