How Louis Philippe's fit compares with mtsya
Louis Philippe labels shirts by collar size and cuts them slim. mtsya is a regular fit with a little more room through the chest and waist, so read the chest numbers, not the label.
Every mtsya shirt is one regular-fit pattern in S to XXL, so once you know your size it holds across the range. A size exchange is open for 7 days after delivery.
How to read a shirt size chart
A garment chest is the shirt itself, measured across the chest just below the armholes and doubled. A body chest is you, measured round the fullest part of your chest with the tape level. A comfortable regular-fit shirt is usually about 4 in bigger than the body it fits. Shoulder is seam to seam across the back. If you sit between two sizes, the smaller one looks neater and the larger one is easier to move in.
