A bit over a year ago, I was wearing only long sleeved pants or long skirts, absolutely nothing that showed leg skin and rarely anything shorter than my elbow and I hardly showed any neck, often had a scarf covering the whole neck. I had a few tops and pants that were slim fit that I was phasing out.
And now, I decided to continue wearing knee-length skirts and recently went to a lake not with my regular semi-islamic bathing suit but with just above the knee pants and a regular 1-piece bathing suit underneath (basically showing more skin than regular tank top). And I was perfectly comfortable! It wasn't a packed beach but there was another couple families there and meh - it was just fine.
I guess I've gotten less strict with my own way of dressing over the past year, little by little.
