I cut my hair from past-waist-length to less than an inch long a few years ago. I didn't tell DH ahead of time. He very wisely didn't say anything until I asked him directly, at which point he told me I looked "one part sexy, one part lesbian, and one part soccer mom." I told him I was happy with two assumptions out of the three (no kids in soccer yet) and he never said anything more about it.
(I'm growing it out again, but mostly because short hair was a lot more work than long!)
