Before you begin, it is recommended that you build a color-coordinated wardrobe that enhances your personal coloring, see Charm School.
Week 1 - Basic Suit in a light summer neutral color and sturdy summer fabric such as linen blend. I'm looking for good fabric and tailoring with a flattering fit as this is the cornerstone of my wardrobe! It will match every other piece. I'm going for soft white or classic white, but oyster white and light warm beige works too. Do the color test when shopping.
