Sometimes it's easy to get comfortable with a certain wardrobe. For whatever reason, this can be a great convenience. But it's important to think about the variation and longevity of your wardrobe.
It's true that things can begin to look worn, having a wider selection of outfits can help ease the wear on your clothes and make your seasonal collections stretch even further.
So don't be afraid to slowly build a wide selection of things you like, it's likely they will combine to make new outfits too!
