I thought about Whitney's situation a bit, and I think she likely won't share the details of her past because it not only involves herself, but her parents. It's their story as well. I can respect the desire for privacy and honestly, I don't care what she did or did not do. I just hope everyone has made peace. it's a terrible thing to not reconcile with loved ones until it's too late.
Not surprised that Whitney wore such a modern dress to the renewal. Honestly, the first wedding looked terrible and it was clear the Bates controlled the whole thing. I don't know what Whitney's style was like before Zach, but I doubt she was wearing ankle length dresses while working at Sonic. I am sure Kelly guilted Whitney into more modest wedding dresses than she would have actually worn. Now, Whitney and Zach are working and can afford their dream wedding, probably make six figures between them, so it is not surprising that they did a modern do-over.
Josie's dress was beautiful. I think it was fine as is and didn't need the modifications that Kelly suggested. It's pretty telling now that if you look at Josie's IG, she's wearing jeans and sleeveless tops now. Kelly may say the girls want to wear modest attire, but it's clear that some of the older daughters are itching to dress like other young women their age. I think Tori, Michael, and Erin have stuck to the modesty rules, but Alyssa, Josie, and Carlin (who had a bathing suit under a cover-up this summer) would prefer not to be super modest.
