Denim shirts are today perhaps the best way to start wearing shirts in everyday life, if you are used to more casual sweaters and tops. The garment is available in all conceivable variants, from models that are just as suitable to be worn with a tie and blazer, as well as coarser variants in a more casual design. Wear your denim shirt with chinos, more formal trousers or a suit where the fabric has a somewhat coarser texture. If you are going to wear your denim shirt with an open collar, variants with a so-called button down collar are a very good alternative as this collar is well suited to be worn open.
If you want to match your denim shirt in slightly more formal combinations, it is very good to combine with other slightly coarser fabrics. Denim shirts work well with fabrics such as flannel, cuffs and tweed. These fabrics and the garments made from them often have a casual appearance in the same way as denim shirts, plus the coarser textures create a nice visual harmony. If you are curious to try wearing a tie with your denim shirt, it is important that the shirt collar in question is large enough. Most collars on denim shirts are too small as they are not designed to provide space for a tie underneath.
