Orders placed between 3rd and the 22th of August will have slightly longer delivery due to vacations in Portugal. We estimate about 6-7 weeks but may differ in either direction.


What is it? It is perhaps best described as a something in between a jacket and a shirt – the casual substitute when you feel like wearing neither a jacket nor a cardigan. Convenient, rustic and stylish all at once. You can wear it over a t-shirt, turtleneck or an oxford shirt. Shirtonomy’s overshirt is made of rustic flannel twill weave (295gr/m2), which gives the right weight and fall. Its other design attributes consist of a full spread collar, large horn buttons, two recessed pockets at the bottom, straight cut at the bottom and single low cuff. (Please note: The design for our overshirts is locked and cannot be altered).

Since an overshirt is not tucked into your pants and needs to leave room for the garments you choose to wear under it, you need to create a special measurement profile that is customized for this objective. Compared to your measurement profile for conventional shirts, please consider the following when creating your overshirt profile:

  1. Chest and waist should be approx. 1-2 cm wider to leave room for the garment you intended to wear underneath it (such as t-shirt, turtleneck or an oxford shirt). We also advise you to use the same measurements for waist and hip to create a straight silhouette at the bottom (less marked waistline).
  2. The shoulder measurement should be increased by approx. 1 cm for the same reason as above.
  3. The length of the shirt (back) should be made approx. 5 cm shorter (depending on how long your conventional shirts are). A good proxy is for the shirt to end the centre of the seat (at its widest point).
  4. The sleeve length should be approximately 2 cm shorter so that it resembles the feeling of a jacket and does not end too far down the hand.
  5. The sleeve width should be approximately 1-2 cm wider to leave room for undergarments
  6. The cuff should be made approx. 2 cm wider to create a more casual look and leave space for undergarments.

Below is a table of standard sizes for overshirs that could also provide you with some guidance. (Please note that these measurements differ from Shirtonomy’s standard sizes for conventional shirts).
