The Cortina jersey on sale now is my favorite jersey, except it only has 2 pockets - but the pockets are really big. Black is better than white, the fabric is really sheer. The Stella jersey is club-cut.

Also, my club uses Primal, and their jerseys run on the small side (probably still too big for you).
