The issue with these lovely ladies that you posted is that I am not built like that nor am I likely to look as attractive in such things. I'm a 42 year old stay at home mom. My daughter is a freshman and my son is a senior about to go to university next year. (Am I even allowed to look that sexy?)

Fashion gurus have stated that women over forty should not wear leather mini-skirts (mine isn't that short but I'll never fit back into it) and you want us to wear those sexy little numbers.

Sorry, I'm a scout leader and if I wore things like that folks might think... well I shutter think what they might think.
Just for the record.... flannel pj's are fun for lounging in but a short silky nighty is much more comfortable. For our twentieth anniversary I bought a lovely little black number.
I have lost about ten pounds but I shall not celebrate until I have a reason to breakout the sewing machine and put those bones, busk and laces to good use.
If I could loose another forty I could even hike the AT with the Venturing Crew.
