Make sure your wardrobe contains the timeless basics–the ones that we all need, such as a basic t-shirt, tank top, jeans, trousers, etc. You do not need to own the basics in every color. In fact, owning basics in 5 colors that you usually wear is enough. You do not have to buy the same shirt in 10 different colors just because “it looks good” because at the end of the day, you will not wear all of them.
