Pocket Droop on Corporate Uniform - How to solve?

[Turk]

I have a set of TPUs - the new double-breasted uniform coat. The breast pocket is prone to sag open. I'm sure that our esteemed readership will have a tip or two on closing this up.

Can I get your help in solving this minor annoyance?

I left mine stiched closed. It's not like you're going to put anything in there. The specialty badge pins are long enough to go through and you can put your hand between the lining and the shell through the slit by the edge. It looks like a fold, but there is an opening.

Sew it shut.
