Use layers to fresh up your online look.
I recommend to use layers as a styling accent.

Outfit formulas:
Grey jeans + Yellow t-shirt + brown shoes (striped sweater)
or
Orange pants + white t-shirt + striped sweater + brown shoes
or
Pants white +white t-shirt + brown jacket + brown shoes

For online:
You can try to wear striped (or any) sweater on shoulders (like on photo) top of shirt.

The main idea of a capsule wardrobe is that all its items can be combined with each other in almost any combination, creating many outfits from a limited number of pieces. This is achieved through:

1. A neutral color palette – basic colors (black, white, beige, gray, navy) that mix well together.
2. Classic silhouettes – universal cuts that don’t go out of style and suit various types of looks.
3. Minimal accent pieces – 1 or 2 statement items that add personality without disrupting the overall harmony.
4. Functionality – each item should work for several situations (work, leisure, evening).
