@RickiTarr I work in a predominantly female office and I hear it all the time - but in a positive way I guess? The girls will comment on other girls if they've got their hair done or eyelashes or if they've been losing weight, working out, etc. Always positive but I often wonder how it would come off if I (one of the few men in the office) would make those same comments.
I never comment on anyone's body/appearance, regardless if it's positive or not. There are other ways to break-the-ice. I'd like to avoid a meeting with HR :)
