Just a sidenote, organising your wardrobe takes time - this should be done on a spare afternoon when you aren't doing anything!
Empty your existing wardrobe and sort items into three piles.
The first thing I do when sorting out my wardrobe is completely empty it. I take out everything from my underwear to my shoes, and give the wardrobe a quick clean - it's not going to get one in a while! It might also be a good idea to add scented sachets if your wardrobe is an old one - before I changed my furniture to white, I always liked to add the lavender sachets to my pine wardrobe to make it smell nice!
I then sort everything into three piles; keep, sell, bin. Obviously, the keep pile are the clothes you wear often and still fit you etc. The sell pile contains clothing you don't really wear often and are in saleable condition - there are lots of Facebook 'Buy and Sell' groups you could sell clothes on, not to mention Ebay or Depop etc. My bin pile contains clothing I have worn to much it has got out of shape or very faded, or the clothing that is too small or too big for me!
Plan out where clothing is going to go.
Before you start to refill your wardrobe, I recommend you plan out where items are going to go. You may want to consider having a switch around where things are kept to make it easier to access. Plan out where you want everything to go, and you may find yourself some extra storage. Once you have planned out everything, why not invest in some compartments for your drawers etc. I have one for my underwear drawer to divide my socks, underwear and bras from each other so they are easier to access.
Put items into appropriate place.
Once I have decided where everything is going, I like to make sure everything is folded and turned the right way out and place or hang them into the appropriate section. In my 'tops' drawer, I then have organised it further into a Jumpers pile, a Fitness Gear pile, Short Sleeved pile etc, which makes it even easier to access. When it comes to jeans etc, I have organised them into dark to light which just makes it look prettier and neater on the shelf! Fiddle around with your items, place shoes in colour order on a shelf etc, until everything looks nice and organised.
