I really don't see the point in getting dolled up to much unless It's to hide a few wrinkles.
The clients are more interested in what's underneath your clothing not the clothing itself.
I'm sure half my clients would be happy enough to see me open the door in my birthday suite.
At the end of the day It's a shag they want not a look at what's in fashion unless It's a overnight or a meal booking your getting booked for x
Not sure what your clients like, but my clients love me dressing up in a nice dress and heels to "look the part"
Most love me in sexy lingerie and stockings as well.
I always get comments on the nice dress I wore or the shoes I wore, so obviously they take notice and like it. I also enjoy getting "dolled up" it gets me in the mood to have fun.
I don't think anyone can speak for what the clients interested in as everyone is different.
Some just want a quick fuck and go, so of course wouldn't mind you opening the door in your birthday suit.
Others like the whole experience of a girl dressed up and being able to undress her slowly... So everyone is very much different in what they like.
