I completely emphatize with you Vickie. It does take courage to stand for yourself and be who you are.
I suggest that you give them an honest feedback about your experience. I say the old lady reacted due to her ignorance. However, that is not an excuse.
I also suggest online shopping for now or go with a woman to shop with as it makes it easier. Buy it and try it at home - if it doesnt fit, return it.
Love,
April
