A while back I was in a Thimbleberries group. Extremely casual. The only time I ever saw anyone wear a dress was a young lady (early 20's). I remember thinking then that when I was a kid and a group of ladies met, they would all wear dresses, jewelry, makeup and nylons!
When I retired I swore to myself I would never ever wear nylons/pantyhose again! The only time I wear nice slacks and tops is for going to a wedding or a funeral. It's been nearly 15 years since I even wore a dress/skirt.
My standard attire is warm weather: jean capri's, feminine t-shirt and crocks. Cold weather: jeans, sneakers and feminine flannel shirts. I have skin allergies so no make up except for moisturizer for sensitive skin and lipstick. And always a wash and wear hairdo!
