Fit Guide

We offer our shirts in two fits: Slim Fit and Extra Slim Fit. Simple. Looser or tighter. With over 40 years experience in tailoring we are confident that these two fits, combined with our 15 size options, will cater to nearly every body type.

Slim Fit

Our Slim Fit is our most popular fit and will fit most body types. If you are in doubt, you should choose this option.

Extra Slim Fit 

Our Extra Slim Fit is tailored to a tighter look and is the right choice if you prefer tighter fitting clothing or have a slender build.

How to choose your fit & size combination:

When you know if you want a tighter or looser shirt, you can use your usual t-shirt size and your height as a guide to select the right collar and sleeve size in the following table:

Tip: if you are on mobile rotate your phone to landscape to read the table easier: 

Note:if you are planning on wearing a tie it is important to choose the correct collar size. See our Size guide for details on how to measure your neck size.


To cut down on potential returns and ensure you get the perfect fit we are offering a LocalFit service in London. If you are not entirely happy with your fit we will come to your home/office/anywhere that suits and measure you and alter your shirt within 48 hours to your measurements. Getting our customers the right fit is the most important thing to us, and if we can reduce waste and the carbon footprint of our products in doing so then that is even better. Contact to arrange a pickup. We will do the rest from there. 

For customers outside of London, we will aim to roll out this initiative across the UK and worldwide in the coming months. In the meantime, we offer free returns and exchanges. Every Alder & Green shirt comes in a potato starch bag and a recycled cardboard box. You can re-use this box and attach the pre-paid returns label to make the return process as easy as possible. 


If you have any questions or further queries on your fit please contact us by email at or via phone/text/whatsapp on +44 776 836 0966.
