HOCOSA has not been able to give us sizing charts, so we have instead measured the garments lying flat to give some guidance in sizing.   Length & your US size will give best guidance - garments stretch easily widthwise. 

 ** Chest measurement in chart below is garment, lying flat, unstretched.   
Fabric can easily stretch 6-8 inches widthwise. 
Use length measurement for best fit.

More about HOCOSA ...

To maintain the health and longevity of your garments, organic wool is best washed by hand.  Many modern woolen items are treated with chemicals to allow them to tolerate machine-washing.  Certified organic wool does not contain such chemicals.  Some washing machines have a special wool-cycle, which maintains a lukewarm water temperature throughout the wash and rinse cycle, as well as minimizing agitation of the garment, which can lead to felting/shrinking.   See Caring for Wool

We recommend hand-washing with Kookaburra Wool WashBottle of Kookaburra Wool Wash

  or LANACare Lanolin Soap with even more lanolin, 7.5%. The higher lanolin content is recommended for nursing pads & diaper covers, or to add even more softness to your woolens and to prolong the self-cleansing properties of the wool.
