Jeans are a great basic because they can be worn so many ways. For casual wear, add a t-shirt, sweater or plain shirt with sneakers or flat shoes. The same jeans can also be dressed up nicely with a fancy blouse or a camisole with a jacket and heels.
Some of the famous clothing pieces are tank tops, turtlenecks, khakis, shorts, slacks, skirts, sundresses and blazers. The styles and colors of these items will also change from season to season. Skirt lengths go up and down, with both a short skirt and a longer style usually in fashion at the same time.
Some get bored of their clothes until it wears out, so pick what you like that fits your budget and consider the durability. Just consider your preferences and be comfortable.
