I like that jacket a lot (though not having seen you irl I can't comment on whether it would suit you), but I'm not sure about the price vs. the number of times you could wear it.

Take it from someone who has a red and white herringbone tweed skirt that cost $300 and a dark grey knife-pleated skirt that also cost $300 -- I love the tweed to death, but there's no way I'm going to get that much wear out of such a distinctive garment. The knife-pleated one gets trotted out regularly.

So I guess the moral of the story is... how often will you wear it?
