Keep the sourced color relationships but change how much of each layer you show. Small adjustments make the three looks useful across warmer weather, long walking days and casual plans.
For warmer weather
The white polo and green chinos provide a light base, with purple in the cap or another visible accessory if you prefer no hat. For the varsity look, a lighter green layer can replace the jacket in warm weather while the white polo and lavender trousers retain the other two colors.
For cooler layers
Mission Layers is the warmest set: the crewneck adds coverage under the track jacket, and the sage chinos keep the bottom half coordinated. Keep the jacket partly open indoors; zip it up outside. The white stripes remain visible either way.
For a more polished plan
For a neater setting, use the white polo, green chinos and white footwear, moving purple from the cap to a small accessory or a lightweight knit you own. The women’s look already carries white, green and lavender through its jacket, polo and trousers.
