With luxurious soft fabric and figure flattering design these Rubenesque Rider long sleeve shirts will have you looking and feeling amazing  in your equestrian pursuits. Perfect alsofor under a jacket or vest. 

I am an 18 in regular clothes and wear the 18 here. I suggest going with your usual size or if you prefer a looser fit choose the size up. The mannequin is a size 16. 
Happy Riding
