Let the palette do some of the work.
Start with colours that sit comfortably together. A rich green with a warm neutral, or a soft rose with a little gold, can make the outfit feel connected before you add accessories.
Style for ease.
A relaxed brief still rewards deliberate choices. Try a simple silhouette, then use a small bag or a considered hairstyle to finish it. In the game, test the look with one fewer accessory and see which version reads more clearly.
Take the idea into a Glam Battle
