My day to day wear depends totally on what I am going to be doing or where and who I am seeing. Jean’s and a nice blouse are the usual, with bra and panties at least underneath.
Dressy casual for occasions like family meals and get togethers such as Christmas eve and day. Christmas eve I wore a very nice pair of wide legged slacks with a cloth sash belt, burgundy silk blouse, low heeled Marbella pumps, and of course the complete ensemble of lingerie, stockings and garter belt, and matching wine colored bra and panties. The other women there wore close to the same level of casual but dressy also.
I always pick the level of my casualness to be appropriate to the occasion, and if I am not sure, I will call and find out how dressy to go.
