Summarize this article:

This is a great option for any student to express their style without breaking dress code. Head to your local thrift store or search online for vintage pins, buttons and brooches. If you want to go for a preppy feminine look, pick a jeweled cameo brooch. For an edgier style, choose a simple button or enamel pin with an animal, word, or symbol on it. Keep in mind that your pins should be school-appropriate. Don't choose a button that has a swear word on it or anything that could be considered inappropriate. One of the best ways to show off your style is by dressing up your uniform with jewelry. Pick a statement necklace paired with simple earrings and a ring or 2. If you aren't allowed to wear necklaces, pick a pair of fun earrings, like tassle or pom-pom earrings to match your uniform. This is also a helpful strategy for drawing people's attention away from your uniform and onto your face. Choose a solid-color, embellished, or patterned headband, and wear it with your hair up or down. If you don't like headbands, purchase a bow on a clip and put it in your hair to hold back your bangs or use it highlight a sleek ponytail or high bun. You can use a ribbon to pull up your hair, or incorporate it into a classic braid. Most schools allow hair accessories, but some might require them to be solid colors. Check your school handbook to make sure. For a cozy and trendy look, put on a wool scarf with a fun pattern in colors that match your uniform. If it's warmer outside, try tying a silk or satin scarf around your neck with a bow for a classic fashion statement. If your school has rules about not wearing hats, they may not allow scarves. Be sure to consult the handbook before you wear a scarf to class. Pick a small, square piece of fabric, and fold it into quarters. Position it in your pocket so the folded corner of the square is pointing up to your shoulder. Be sure to choose a fabric that matches with your school uniform or tie. For an edgier look, try mixing patterns, like stripes and polka dots, or use a pocket square that showcases your interests, like one printed with binary code if you like computer science.
Pin a button or brooch onto your blazer or shirt for a retro style. Wear statement jewelry if your school allows it. Put a headband, ribbon, or bow in your hair for a classic feminine look. Wrap a trendy scarf around your neck in the autumn and winter. Tuck a pocket square into your blazer for a classic masculine look.
