I have. Takes some thought but great fun too and huge bonus in basically having an easy time getting dressed almost every day. Decide a style or look: classic, romantic, sporty, dramatic or whatever.
Decide colours - base colours and accent colours.
Cull wardrobe accordingly, then buy any necessary fillers.
Also shop for your actual life.Now I basically wear charcoal and navy as a base, plus denim. Orange, teal, mustard and pine as accents. Plus white. I have a wardrobe that is good for work and at the weekend as many of my clothes can be dressed up or down with different shoes, makeup etc.
I still have the odd bit of proper formal wear tucked away for occasions - a pair of heels, a good suit and a black cocktail dress.
I sometimes add in a frivolous item because I like it - like an easy summer dress once summer finally arrived. Or the odd thing I know I'll just have fun either for a season or 2. I have a silly comic book skirt that makes me giggle- I wear it when life gets too serious (dh laughs at me but I love it)
I started with shoes and basically realised I never wanted to have to wear uncomfortable shoes again. I realised this was totally doable in my work context so then it was what can I wear that looks good with the brogues and boots I will wear?
My pared down wardrobe helps me realise when I'm getting too uniform as well. I can see it sell in one go so now i notice that I have bursts of buying essentially the same item again and again ending up eith 5 grey jumpers or whatevers. Now I think do I need more than 1 navy short sleeve top? The answer is usually return it and buy a grey one instead. Or something striped. Then I have an unobtrusive top which is what i wanted but a more varied wardrobe. I love not having endless clothes I never wear. Plus at leadt 75% of my clothes go with each other and most days I'm pleased with how I look.
Sorry im going on and on but this is the best thing I did for myself in years
