Jupiter rules your sign and, because of its expansive nature, can make you a bit of an impulse buyer, and hoarder by nature.
It's not that you want all that stuff. Like fellow fashionable Sagittarius Taylor Swift, you just move so fast, you sometimes don't have time to go through it all.
Making regular times - every six months might be good - to purge your wardrobe and cosmetics supply of seldom worn items not only lightens the load for your next move.
It makes space in your drawers, cabinets, and closet for more purchases down the line. Your generous nature is only too happy to give your stuff to charity or a friend.
