Forget your entire look if you don’t have the proper undergarments. Start out with properly fitting undergarments. They truly are the foundation of an outfit.
Do a wardrobe assessment. Know what you are looking for. Go rested. Go alone.
Take more than one size to the fitting room. Look for color and fabric first, then silhouette, and then the size.
Let the salesperson know what you want. They are there to help.
Do your research. Go to stores that have merchandise in your style, size and price range.
While shopping, think outfit, not item. Before you buy, think: does this item have friends in my closet?
Do not stint on your core pieces. Invest the best you can bring yourself to afford. Concentrate on fewer, better pieces.
