This is the capsule wardrobe plan used by Jennifer L. Scott of The Daily Connoisseur blog.
The 10 item core wardrobe includes trousers/jeans, skirts, dresses and some tops (but does not include outerwear, exercise/activity clothing or sleepwear). This is supplemented by a range of extras (t-shirts, sweaters, cardigans, outerwear, shoes and accessories).
The 10 Item core is changed 4 times a year [Winter (Jan-Mar), Spring (Apr-Jun), Summer (Jul-Sep) and Autumn (Oct-Dec)]. Around the changeover from one season to another, the core wardrobe will also have a couple of transitional items: for example, at the end of the summer season there might be a warmer sweater and a heavier weight trousers, while the autumn core might also have a summer dress and top for warmer days.
Example Fall/Winter Wardrobe: wrap dress / print tunic / 2 x silk top / print dress / tank (pinafore) dress / tie front blouse / peplum sweater / skinny jeans / crop linen trousers.
Example Spring Wardrobe: 3 x short sleeve sweaters / long sleeve sweater / 3/4 sleeve cardigan / trousers / tailored shorts / A-line skirt / pencil skirt / jeans.
