4. Blazer + T-Shirt + Slim Trousers

For instant sophistication with minimal effort, layer a tailored blazer over a classic t-shirt and slim trousers. This combination effortlessly blends casual ease with polished structure, making it perfect for workdays, meetings, and even weekend outings. Choose a neutral-colored blazer for versatile styling, or opt for plaid or bold colors to add personality. Pairing it over a simple white or black tee ensures a relaxed yet refined look, while slim trousers keep your silhouette sleek and modern. Complete the ensemble with loafers, heels, or clean sneakers to seamlessly transition from day to night.
