The "dress" looks like a little cover up you wear at the beach nothing too scandalous, the show is set at the beach.
I'm not a fan of some of the outfits girls/women get around in nowadays,
but I put that down to being old. I saw a photo of me at 16 going to a dance and honestly wondered how I was allowed out the house .
I don't think I have ever dressed to please or titillate the opposite sex (or the same for that matter). Available or not I've always dressed in what I've thought (photos have proven some lack of judgment) I look good in. I dress for me.
