All of these are cute casual looks Archie so it is difficult to pick. How many items do you want to include in this capsule?
Ironically I was just contemplating building a dressy capsule. Here is the process I came up with. Me, I always need to have a plan Maybe it will help.
- List the events I want outfits for and what I could picture myself wearing. Maybe you could pick out an outfit from above that you would wear.
- Pick several bottoms/dresses keeping in mind how much variety do I want/need (pants + skirt or just pants? any dresses?) and how formal do I want them to be (in your case casual). Since you prefer more dressy looks the paperbag bermudas, the yellow and grey ankle pants, the black stripe culottes, and the skirt jumped out at me over the denim pieces.
- Then pick tops and toppers to mix/match with the bottoms.
