My wardrobe tends to be classic and understated. I like clothes that flatter me and are comfortable. No, that does not include sweats, leggings or teeny tiny skirts. And, forget about the "jogging suit"!
What you should do is find what fabrics and colors appeal to you and flatter you. Start with the basics, a couple nice blouses or tops, a skirt or pair of capris and a pair or two of pants. If you insist on wearing neutrals for your entire wardrobe, you will just fade into the background and look dowdy. Save those for your skirt and pants. Use the blouses and capris to add color and bring your look to life.
Later, as you gain more confidence and learn what flatters your body type, you can experiment with different fabrics, colors, trims and other details like neckline treatments, seams (like princess or darts) and hemlines.
Good luck!
