a: measure shoulder width from side to side at widest position.
b: measure upper arm circumference.
But the sizing is actual not too difficult since the models are also adjustable in size.
Best orientation is your -t-shirt size, if you wear S or M t-shirts then go for size S/M (size 1) with our holsters.
If you wear t-shirts in size L or XL then go for our holster in size L/XL (size 2)
please note the holsters are unisex products therefore we recommend: girls always go for the smaller size (size S or 1)
