If you’re not familiar with a “capsule wardrobe”, it is a set number of clothes that can mix and match with one another to create many outfits.   Typically, you wear a capsule wardrobe for 3 months, then at the end of those 3 months, you update it for the next season.  By having a set number of clothes per season, you limit your shopping, thus saving money!  When a piece is worn or doesn’t fit right anymore, then shop for a replacement.  You will find capsule wardrobe ideas everywhere on the internet, including here on ClassyYetTrendy.com.  I also sell several seasonal capsule wardrobe e-books in my Capsule Wardrobe e-Book Store.
