A soft autumn’s pink is soft and muted. I would call it a dusty pink. This is a triad color scheme from the soft autumn color wheel. The colors form a triangle on the color wheel. Teal would be the third color. This dusty pink paired with the mustard yellow is a perfect color combo for a soft autumn. I paired deep chocolatey brown pants with the outfit to keep the outfit warm.
Here’s a soft autumn outfit I found with a blouse in this same shade of pink. You can always keep it simple with jeans and your main color.
Have fun and wear what you love!
