A really nice Brooks Brothers sport coat, in a 43L, which isn't the easiest size to find.

According to the Brooks Brothers web site, the Fitzgerald cut is a slimmer cut than, say, the Madison, with narrower lapels and higher armholes.

Notch lapel, two button front with four on each sleeve, single vented in back. The usual three front pockets, with three on the inside. Fully canvassed and lined, Italian fabric, with fairly light shoulder padding.

Measurements, laid flat and not stretched:

Shoulders (between tops of shoulder seams) 18.25 inches
Chest (pit to pit) 22 inches
Midsection (slightly below top button) 19.75 inches
Hip width (about 6 inches below bottom button) 21.25 inches
Center back length (from base of collar in back, to bottom) 31 inches
Sleeve length (along top, from shoulder seam) 26 inches
Sleeve bicep width (about 1 inch below armpit) 8 inches
Sleeve opening 5.75 inches
