    Frequently Asked Questions

    What shirts are essential for a men's wardrobe?▾

    A white Oxford that works casual to semi-formal. Light blue for variety. Chambray or denim for weekends. A dark navy for evenings. Quality tees in white, black, and grey. Five shirts and three tees cover 90% of situations. Get the fit right first, everything else follows.

    How should a men's shirt fit?▾

    Shoulder seams at your shoulder points. Enough room in the chest for a flat hand when buttoned. Two fingers between the collar and your neck. Sleeves ending at the wrist bone. If you're between sizes, our AI stylist can suggest brands that run closer to your proportions.

    What is the difference between casual and formal shirts?▾

    Formal: stiffer collars, finer cotton, solid colours, longer tails for tucking. Casual: softer collars, relaxed fabrics like Oxford cloth or flannel, straighter hem. The fabric and collar formality matters more than the colour. A soft-collar shirt in white reads casual; a stiff-collar shirt in pink reads formal.
