Honestly, your best bet is to find a bike shop that will let you try different saddles, or return/exchange one that doesn't fit. Another option is to buy cheap used saddles (often take-offs) on eBay and resell them if they don't fit. I probably tried 10 different saddles before I found one that fit me best. I then bought a bunch more of them on eBay for cheap prices for all of my bikes. FWIW, I've had good luck with Fizik Vitesse and Vesta saddles, which are marketed as women's saddles. They are similar in shape to Fizik men's saddles but wider. I must have wide sit bones because standard size men's saddles are always too narrow for me. I also had good luck with the Brooks B17, but the Fizik saddles are just as comfortable for me and weigh less than half as much.
