09-04-2026 A really good-looking shirt with a great fit — it sits perfectly and feels very refined. Looks excellent with a dark navy blazer. I’ve had nothing but positive compliments on it; in short: highly recommended! Albert

04-01-2026 Just like all shirts from OLYMP, you know what you're getting: fantastic material and a perfect fit. This model does have some odd points at the shoulders due to the packaging method that are tricky to get rid of. B
18-12-2025 Perfect shirt for both casual and business occasions. Typically not a fan of shirts made entirely of synthetic material, but this shirt feels like a cotton shirt with stretch. R
14-12-2025 Truly a delightful shirt. Should have done it much earlier. Nicely tailored, great fit. Lovely material with a bit of stretch. Fantastic price too. B.

Given that the collar of your shirt draws the attention of others to your neck and jawline, it determines the look of your shirt. If it fits and compliments your body structure, you will appear well groomed and streamlined. This is especially handy when you plan to wear a formal suit. Collar size 45 is specifically meant for men with a wide neck and is sometimes referred to as ‘Extra Extra Large’, XXL or 2XL by some suppliers. If you have doubts as to whether collar size 45 suits you, feel free to contact us. You are also welcome at one of our Suitable stores for personalized advice.

What is my actual collar size?

Our colleagues are always ready to measure it for you, but it is also easy to do it yourself. Simply wrap a measuring tape around your neck, just below your Adam's apple. Make sure the tape is not too tight or too loose, and leave half an inch room for manoeuvre. That's approximately one finger width. Then read off the number where the tape crosses and you have your size. If you regularly wear a tie or bow tie you can add half a centimetre for extra comfort.
