Beautifully designed oversized tee. Perfect for during or after your yoga classes. 
Or great to wear day to day.  Get all cosy for savasana...
 
They are beautifully unisex - perfectly masculine and feminine all at the same time. 
 
For male sizing, I can recommend choosing your usual sweater size, or drop a size for a closer fit. 
 
For female sizing, I can recommend:
Size S  8/10
Size M 12/14
Size L 16/18
 
However do feel free to swing up or down if you prefer a closer to body fit, or a looser look.
