What a fabulous summer wardrobe! So chic, breezy, and feminine. I am inspired! I too want to see you in that tuxedo jacket!!
For autumn, I think any kind of corduroy or velvet is a wonderful addition! I also love a good animal fiber cardigan for autumn/winter. (Alpaca, wool, mohair, cashmere, and various blends.)
I am toying with the idea to add a knit vest. So, a vest might be another idea for you? I haven't really seen them gaining steam for trends. But with 90's styles having a renaissance, I could see a vest being a great addition.
Boots are always welcome. Another option is a velvet smoking loafer.
For winter, I personally get a lot of wear out of
- dress and wool topper.
- jeans/pants/skirt, blouse/tee, and wool topper
- jeans/pants/skirt, turtleneck, wool scarf, maybe a topper
Writing it out, the aforementioned doesn't sound exciting. It's obviously a skeletal formula open to imagination and interpretation.
