Last winter, I embarked on my first capsule wardrobe.
One of the main virtues of a capsule wardrobe is simplicity. You only have 37-ish pieces to choose from for one whole season, thus (in theory) cutting back on the number of decisions you have to make and therefore the amount of time it takes you to get dressed.
One blogger who helped bring about the resurgence of the capsule wardrobe, Caroline Rector, explains it this way on her blog, unfancy:
To me, a capsule wardrobe represents more time and energy for what really matters (less time spent deciding what to wear/less time spent shopping/less time doing laundry or caring for clothes) more money for our dreams and helping others (less money spent on clothes that never get worn) and more contentment and happiness.
