Texture is something we forget - it makes outfits look very expensive. You can do a monochromatic outfit, if you're afraid of things that are more colorful and printed, and still create interest.
Style is not a reward for the skinny. It's not, 'iI I'm rich, thin and young.' You may not like your size, but then don't invest in leather leggings. Let yourself want the expensive bag and really love it and show it off and have a ball with it.
Rules like 'don't wear white after Labor Day' or 'shoes matching the handbag' are antiquated. Modern women should feel free to experiment.
I don't argue style on the basis of tastes. If you feel like you've reached your personal best, don't change.
