Our sizing system is designed to help you find the right size without the need of trying the products on in person. You can visit Find Your Size to see a comprehensive step-by-step guide on how to measure yourself and get accurate measurements.

Our Dress Shirts come with removable collar stays, which keep the collar firm and even. An extra pair of collar stays are also attached to the hangtag.

We use a spread collar design on our dress shirts is because it fits almost everyone, regardless of their build and face shape. It also looks good whether you wear the shirt with or without a tie.

The sleeve length of a ‘plus size’ Smart Casual Shirt is around 4cm longer than a ‘non-plus size’ one, with all other measurements remaining the same. Click here for detailed information about our product sizing and measurements.

We do not recommend bleaching or dry cleaning our shirts, as harsh cleaning methods can potentially weaken the wrinkle-free properties of the shirt. We suggest using laundry whiteners as an alternative to bleach. Please refer to the care label for more detailed wash instructions.
