She is daring! Her confidence is exactly the reason why her outfits work!
Imo, she has a true understanding of style. Her's is singular, and Sheila's "a little of this, a little of that" presentation may (conceivably ... ) personify who she is. Arguably, you can learn something about a person by the way she dresses. I'm an admirer of her wardrobe choices in any case.
Can anyone identify the pullover in the last pic posted?
