To get your true fit, lay a well-fitting garment you currently own flat onto a level surface.  Measure across the front only from armpit to armpit and then vertically down the exact middle from neck to hem to find your closest match. 

If you want a looser, slouchier fit, we suggest you size one up from the true fit described above.

Due to the naturally malleable properties of wool please allow for a tolerance of 2-3cm.
