Images in the 2nd row are me. I'm 5'10" and about 150lbs. I wear size small in our jackets and shirts. On the waxed truckers I like longer sleeves as they tend to slide up as you get creases around the elbows and the wax keeps the creases up.
Stock store access is generally pretty limited. We try to get people access who need to swap a garment out or more broadly when we happen to have some extra garments. That's why access is not open all the time to everyone.
Apologies for this. Definitely shoot a note to support and we'll take care of you. I'll check if we have one on hand for you right away as well if you let me know the size you ordered. You can PM me or post here on your size.
