Ample Cross Back Aprons!

I've just listed a few of my bigger cross back aprons on Etsy, 

 I had to wait for a willing model!

Small, medium and large means absolutely nothing to me, there is no size definition. 

I'm a 10/12/14 depending on the label. On my bigger sizes I want for 'ample' and 'more than ample'.  The measurements are listed in inches.

Top to bottom these are denim,  heavy linen and pinstripe denim.
