Tweed jacket with gaping side vents - is this fixable?

[lukescic]

I received a lovely tweed jacket from Walker Slater the other day in 42R. Fit is fine in the shoulders, a bit tight in the waist. One or the other of the vents gapes slightly, however, causing one end of the flap at the back to stick out. If I adjust it, the other side sticks out instead. The problem diminishes when the jacket is unbuttoned.

Is this something that can be fixed by letting out the jacket at the centre seam? I think sizing up would lead to an ill fit at the shoulders.

Let the center out, assuming there's enough material to do so. The cut is just too tapered for your body.
