Not attempting to be a fashionista here but given that you are 4’-11’, size 14 and a C/D cup a belly band with a slash pocket access might be an option. At 50 something the girls might cover a great many indiscretions. As I understand it from my wife who is a fair seamstress in her own right a 1/4" Velcro fly (Yes ZZ Top) can be sewn into just about any dress right, left or center.
Concealed Carry often comes with a tailor’s bill. Me personally I have been aerodynamic all of my life and yet I can carry full size 1911’s and similar with no issues given proper cover garments. In suits I have a tailor that knows how to add “panels” to make things disapear, hang level and not flag or bulge. He is a bit pricey but the quality is always worth it.
Not trying to get personal just trying to help with things I have seen done. I got scolded by @Zee for not addressing “girl” issues head on and I am doing my best to rectify that training deficiency.
