This is what separates 1988 from today: how much a garment is body-conscious. Newton, who (with Lily Chin) has probably taught more knitters about the importance of ease than anyone else in the world, recommends a colossal 12" of it in this jacket. So it looks like the wee model is wearing a fuzzy refrigerator. But what if you knit this closer to your own size? It's a good size range, and the style itself is actually a fine one. As always, it's a question of proportion and perspective. La Gran is worked double throughout, and its gauge is given so; the boucle trim is not.
