As of today, forever after, I will save myself $10 per jacket taken-in, as I have figured out how to correctly redo the vent overlap and crease, so that the vent flaps lie correctly. It takes all of maybe 5 minutes, and that includes the time it takes the iron to heat up. I totally understand why it's not included in having a jacket taken-in (and, I'd assume, let-out; the issue is probably the same, just opposite), as it's a nice little profit center. Of course, that $20 includes a full press and crease, but I have a good steamer and iron, so the vent work was what I was really paying for.
