Lyn, that strategy is so many kinds of awesome I can't even count them. It won't be fun, I'm sure, but it will be the right thing to do, which atones for much inconvenience. Her comments to you were absolutely uncalled for, and if she's saying worse to other colleagues she needs to be nipped in the bud, like, yesterday.
What an interesting assumption she made. If she'd made the remark to me I would have been floored, but because she would have hit the mark. I *am* insecure, and I *do* look to fashion to bolster my flagging confidence. I suspect that's not the norm, though, and why she would project her own issues through the channel of personal style is baffling to me.
Good luck on monday. Oh, and wear the fab boots, too.
