This is a quality suit. 100% wool. Resistant to wrinkle but doesn't feel like the scratchy mess "non-iron" stuff often is. Jacket tag says 37S but I generally wear a 38 (in J Crew Ludlow suits, for instance) and this fits and measures the same as those, so I've listed it here as 38S. Pants are 30x32. The measurement photos and the others were taken at different times—the more true-navy-looking photos are the accurate color representation, not the more gray-ish ones.
