Actually I disagree.
Opinions and critique regarding clothes and attire cannot be regarded as "personal" when we are on a clothes and attire forum.
The first fit I ever posted on SF received a response along the lines of "the suit might possibly be acceptable, although it's hard to tell from this photo. Burn everything else. With fire."
Too harsh? Unhelpful? A personal attack? None of the above. It was a bad fit, fully deserving of the opprobrium. Yes, I felt somewhat insulted. But I was also motivated by it to try and lift my game.
Anyone who posts outfits on this board is, by doing so, inviting criticism of what they've posted.
From what I've gathered, since a lot of the more influential members have left, the average age on here has continued to skew younger. Not to make blanket, vapid statements, but I have found that younger people have a harder time taking criticism without getting unnecessarily defensive. On the show The Crazy Ones, there was a rather comical bit about this very thing.
