Any of our shirts can be tailored to be a casual shirt. Some of the features that distinguish casual dress shirts are shorter length (to be worn outside trousers) or french cuffs (worn unfolded) both are options that we offer. Additionally you can have a casual dress shirt designed to be worn outside your trousers with a square bottom and vents. Short sleeves are also a hallmark of casual shirts and we offer that option as well, in fact, we can tailor any custom options that you wish. If you believe that the fabric of the shirt is the determining factor, we offer some patterned fabrics that are ideal for making casual dress shirts. We also tailor shirts for men out of Linen or Thai Silk which are ideal if you want a casual, yet sharp look with your shirts.
