Hi Eva,
I feel quite a lot of resonances to your situation from where I was just over a year ago. Both my SO and a visitor said that the first day all they saw was the clothes, then after that they saw the person and the clothes became irrelevant. What this translates with liberal people is that they'll have a little shock then become used to it. When she sees this does not diminish the masculine but grows your relating in even better ways you can be onto a winner.
I feel the following points are key:
1. to show that while dressed she is still the focus of your arousal and sexual interest - that actually the dressing increases this attention you have for her.
2. there are massive plus points in the level of relating and shared experience "girl to girl" giving you both a richer relationship
3. still provide macho time for her
4. being open about it is so much better than hiding/sneaking/lying - perhaps say you're exploring this and that you're 100% hetero and so on.
