To wear this set, first put on the shorts. Then layer the vest over it, and finally, throw on the blazer. You can pair it with some nice heels for a more formal look. When it comes to care, it's best to dry - clean these pieces to keep their shape and color. Avoid washing them in a regular washing machine as it might damage the fabric. Also, when you're not wearing it, hang the blazer and vest on a hanger to prevent wrinkles, and fold the shorts neatly. Keep them in a cool, dry place away from direct sunlight.
