I wouldn't call myself a minimalist. My makeup bag is full of stuff I don't use, I don't have fresh white, pillowy sheets on my bed, and you won't find an Instagram full of "candids" from me. But one minimalist-inspired process I have recently began is the trimming of my closet. I gave away most of my things and kept only the necessary closet staples- such as a plain white tee, fitted skinny jeans, a good pair of booties and so on. Now when I shop I don't purchase something just because I think it's pretty; I'll only buy it if I have several outfits in mind I could create with it and if I know it'll last more than a season.
I assumed that styling would be boring and repetitive with a minimal closet; it has been challenging to avoid re-wearing an outfit within the same week but it's encouraged me to get creative and think outside the box. I'm a big fan of black, white, and gray pieces because they make it so easy to put an outfit together! I avoid being monochromatic and I'd recommend buying items with different texture or style so that the ensemble doesn't become too muted. And no one ever said that a minimal style could only be neutral colors- I have my eye on a burgundy colored coat and a pair of snakeskin-printed heels! But anyway, minimalism can be fun and it also wouldn't hurt if most of us downsized a bit in our overflowing closets.
