It's asking me for glittering jewelry but what does that mean?

I gave mine an item from All That Glitters - I got it from a quest so it didn't cost me anything. (Can't remember what it was, though).

Have a look in the shop for anything you think could be classed as glittery then search for it in user shops because it's likely to be a lot cheaper. Also, look through your own shop to see if you have anything.

Thanks. I looked in the pawn shop and then got a cheaper one in a private shop. Mind you I ended up with a male when I started with a female but not sure if that is an issue yet.

you just need to bring any item from All That Glitters. the gender is randomly determined when you visit the zentu bath page - the text will say "a male zentu is bathing" or "a female zentu is bathing" - and may change if you refresh or revisit the page.
