FI, first I chose a bottom, based on the weather and what I plan to be doing that day. Colors of bottoms are way more varied in S/S, as is the type of bottom, since I have skirts, skorts, and shorts. Colors of the latter are neutrals as are the rest of my items, with the exception of a couple of extras in this season—a few pinkish coral items (midi skirt, sleeveless button-up, and cropped pants), and non-olive greens (two skirts). Mid-toned blues make up a significant portion of the color array in my S/S clothes though it does not appear in F/W, as does white. Summer is the only season I will wear optic white. The rest of the time, I prefer a sort of grayed white or canvas. I often do a column of color, which I love, across the seasons.
In F/W, I only wear jeans or other pants; color palette for bottoms is a little less varied, but F/W is where I have my plaid pants. Probably 90% of my F/W pants are either black or mustard; olive, chestnut my few plaids make up the rest. If I don't do a column of color, I resort to certain color combinations that I enjoy, like mixing cool and warm olives (oops, column of color), olive and black, brown and black, copper and black, copper and mustard, chocolate & chestnut, mustard & black, mustard and brown, mustard and cranberry, cream and gray, cream & black, olive and cream, and so forth. Because I look for items with texture or architectural shapes or details, I am never bored with dressing. It's easy and I have more variety than I know what to do with.
In F/W, excitement comes with shoes/boots, toppers, scarves and bags. In S/S, to hell with excitement; I'm just trying to stay cool and decently covered enough for public viewing!
