Hi Danielle10:
After reading your introduction post, I have some suggestions.
It's best not try on or wear your wife's clothes without her permission. Better to get your own clothes. There are many thrift shops, such as Goodwill, where you can purchase, and take home to try on. Be sure to check their return policy. Most will allow you to return the clothes within a certain period of time.
After the talk with your wife (depending on her reaction), if you suggest a night out with her, you may want to refrain from calling it a "girls night out". If she is on board with going out while you are cross dressed, just enjoy the experience but don't pretend that you are "two girls". Of course, you will know better after your talk how to proceed. In her case, she may enjoy the girls night out scenario.
As others have said, be honest, be calm, and don't hide anything. This involves knowing how you feel about yourself and about her. Tell her that you love her and cross dressing is no reflection on her as a women.
The stickies have a vast amount of good information. Good reading.
Best wishes to the both of you
