Keep the palette, then change the layers and footwear to suit your plans. These are ways to adapt the three looks above, using pieces you may already own.
Warm Weather
Start with Patchwork Weekend: the pink tee and teal shorts keep the color story clear with fewer layers. A loose front tuck shows the waistband without making the whole outfit feel fitted. Carry the patchwork bag if you want the yellow accent without a cardigan. If you prefer more coverage, try your own lightweight teal trousers or a loose midi skirt. Choose shoes you already enjoy walking in; a character-inspired outfit does not depend on one exact sneaker.
Cooler Days
Use the cardigan or color-block overshirt as the layer you can take off. Keep some pink visible at the neckline or through an open front so the outfit does not become a single block of yellow or teal. With the skirt look, plain black tights can connect the hem to the ankle boots. For a colder outing, your own neutral coat can go over everything; the bag, lower half and visible neckline will still carry the colors.
A Dressier Version
Choose Patchwork Daydream when you want a more polished silhouette. Tuck the tank neatly into the skirt and push the cardigan sleeves back slightly to make the layers feel intentional. The pleats provide enough movement without extra prints. You could swap the lace-up boots for simple black flats or low heels you own, then use either the patchwork bag or a plain bag according to how noticeable you want the character reference to be.
