First of all, why hide it? If she's cool with the bra thing, is there going to be much of a jump for you to say that it's actually satin clothing in general that you like? My guess is that it won't be....Has she seen you in your bras? If she has, I doubt she'd be too shocked to find that your fetish extends to other garments. I know it feels like a high risk move telling someone you like satin, but I've always found you don't get anything without asking
Is she cool about wearing satin for you? If you've not broached the subject, what about asking if
she would wear some as a first step. Even though there will probably no big fetish element for her, I've never met a woman who outright said 'no I don't like it'. Remember that a lot of the garments we get off on are made to make a woman look and feel good, and some are made to look downright sexy - so it's not normally much of a push to get a woman to wear something that makes her look hot
In my situation when I first told previous partners about my satin fetish, I'd buy a nightie, tell her how much I liked her in it, and let her know how much it turned me on. At some point I would take the next step and ask to try it against my skin and gauge their reaction. If it was OK, all good - If not, I'd keep it at the level of trying to get them to wear it, and get myself a masculine satin garment like a dressing gown and make do. Strike rate is 6 to 1, as in 6 approved and let me indulge, and 1 wasn't into it so I never pushed it.
With my wife, it never got that far, because I blurted out to her that I liked to wear it on the second night we were going out. I'd known her for a year previously and she worked in a department store where I bought my satin clothes under the pretence of them being for my ex girlfriend so the first night I went out with her, she was wearing satin because she thought I'd like it - and that was that - satin based fun ever since
As for what to get - are you into soft flowing satin or tight fitted satin? Dresses or Skirts? If you're not 100% sure yet, have a look around e-Bay and see what you like or think you might like to try on. Just type in 'satin' as your search criteria and work through all the categories like dresses, tops, nightwear etc. and see what floats your boat.
Even better - if she's on board with your idea, why not see if she's into the idea of choosing some clothing with you? I get a big kick from shopping for satin with my wife - both online and in shops. And it means we get things that we will both like
