Naturism/Costumes on Pakleni islands?

We're planning on spending a couple days on Hvar around mid-Sept and thinking of going to one of the Pakleni islands just off from Hvar - Jerolim, Marinkovac, Sv.Klement etc.

Are these three islands still mainly naturist, or are they becoming more textile?
I got the impression from a couple books I've read that Jerolim purely is naturist, Sv.Klement/Palmizana more costumes/clothes-optional, and Marinkovac somewhere in-between with a naturist/textile mix - but am I right?

I believe there's 3 coves/beaches on Marinkovac - Stipanska, Mlin, Zdrilica. Are all 3 ok for naturism, which do you recommend?

We'd prefer a naturist beach but don't mind if things aren't fully naturist, so clothes-optional beaches ok so long as there's a good 40-50% naturist presence.
