So here's my closet before. It's already pretty organized since I regularly groom it. I find it soothing. Also, for the past 10 years, I've worked with closets that were three feet wide. The discipline required was valuable. Compared to what I had before, this closet feels like a Home Depot aisle.
The main changes were decorative, inspired in part by Nicole Balch's closet makover at Making It Lovely. I liked her glass wig head and jewelry tree.
The 'jewelry tree' is a candleholder my mom picked up at Goodwill years ago. The drawback is that I have impaled my hand more than once on those wrought-iron leaf tips. The wighead and scarf were freebies. The sunglasses are vintage via my mom. (I got the idea about the wighead after taking most of the photos, so sorry about the now-you-see-it, now-you-don't effect.)
Here are some of the organizational details: I hang clothes first by item then by color, jackets and shirts on one side, sweaters and skirts on the other. Out of season clothes go in the back corner of each section.
I have mirrored metal bi-fold doors. Long items like dresses and raincoats are hung on the back with magnets.
Out of season shoes go in pretty shopping bags or beach bags.
Little purses and my horde of decorating magazines go up top.
Belts and jewelry below. I leave the other two dresser drawers mostly empty. After any cleanup, you need to leave some empty space for your dump zone. Otherwise you will dump new things on your closet floor, which is an aesthetic no no.
Here's my secret to not overstuffing the closet - I limit the number of hangers I own. I'm Joan Collins about it. ("No wire hangers!") Also, since I'm a little intestinally retentive about my closet in general, the colors matter - I only have black, brown, white, pink or beige hangers. Which is pretty similar to my wardrobe (plus a little green.)
OK, now you can get some chips and go sit on the balcony.
