To answer your question, I place no restrictions on my wardrobe. There are colors that I love, which typically tend to be neutrals, and they are widely represented in my closet. But if I have a desire to step off the neutral path, as I did a few years ago with lilac, and more recently with cream, I do that, with no self-recriminations.
I have a limited number of jackets (3) because I don't really need them. But I was interested in wearing a longer jacket this past winter, so I bought an oversized one to wear over beefy sweaters. There are shapes that appeal to me, ex., cropped and boxy tops, which go well with my preferred high rise pants/jeans plus the few ancient pleated skirts I have, and my eye is always attracted by those kinds of tops.
Even though I don't need skirts, and I stopped buying black a number of years ago, in December I happily bought a beautiful knitted black skirt from an Icelandic designer.
I love high neck anything, and sleeveless items, so again, my eye is always drawn by those whenever I see them. I have realized that much more than color or shape, what drives my wardrobe choices is comfort. I am most comfortable in high rises, cropped (but non-belly baring!) tops, high necks and sleeveless tops. I imagine these things will always feature in my closet. Until they don't. And that's just fine. Because I don't like limiting my options, I am open to experimentation as long as a garment is comfortable.
