Pick the focal line
A column skirt or clean ankle boot can give the outfit direction. Choose whichever piece you want to emphasize and let the others support it.
Edit the layers
A closer top can sit neatly with a straighter skirt. If you add an outer layer, check how its hem relates to the skirt length rather than assuming every proportion works.
Carry only what fits
A compact bag can keep the silhouette light. Confirm the interior dimensions against the items you will take, and choose footwear from the actual fit information.
