I've talked about revamping your wardrobe as a simple approach to dressing for work. The reason I went with a neutral black, white, grey and colorful dresses was boredom and tedium trying to decide what to wear to work every day. I would get up in the morning and toss clothes on my bed.
This fits, this doesn't fit. This is too tight. This color combination works but oh hell, the zipper is broke. These pants make me look fat. This shirt is 5 years old but at least it fits. It was taking me 15 minutes every morning trying to decide. Even when I put clothes out the night before, by morning, I wasn't feeling what I had set out. So I kept pulling out more and trying on more. I didn't want to start showing up to work late just because I couldn't figure out what to wear.
If you go through this each day, you start to realize how much time and energy you waste and your day hasn't even started yet. I needed a better plan.
My plan was to streamline my wardrobe. I get that everyone can't just go cold turkey and donate all their clothes in one shot. But, unlike you, I tossed everything out right away, without delay. Probably should have planned it better because we were traveling to New York for vacation and I had thrown out all my clothes except for a few items. And these were mostly dresses and work clothes.
I've since gone shopping twice for more black and white clothes and actually find this kind of fun. I know what I'm wearing every morning. It's now my signature style. I haven't worn any of the colorful dresses that I own to work yet. I have fully integrated the black, white, gray and have had compliments on my color choice. But don't go with my color scheme. Pick your theme and go full range with the tones.
But once I made the decision, I was stuck with it. That's why I'm saying go slow. Use these tags to decide what you'll keep and what you'll discard. And take your time unless you want to max out a couple of credit cards. Which I'm happy to say I didn't do when I made this switch. I'd like to hear how you've made the change.
