Help with summer clothes?

I am a guy who has had a progression to wearing women's clothes. I now wear women's pants and a blouse every day ranging from very discreet to work to lacy at other times. I do not try to "p" as a woman with makeup or wigs. With summer coming I am looking at swimsuits and would like input from ladies as to what would be the most conservative suit I could wear and the best place to shop for them. thanks for your input.
