I will be seeing a expensive provider soon, for the first time. Her website has various gift suggestions. Should I bring a gift or maybe a bottle of wine. I should not have to impress her, but I do want to make a favorable impression. Please advise, thanks in advance for any advice.

for an hour or so.  You'll impress her more if you are clean, respectful & follow the instructions on the approach & donation.

if it is a lady I have seen before or the date is a multi-hour date.

I have had gentlemen bring gifts  for the first time meeting them.I was pleasantly surprised I do not have a gift list on my website,but they bought things they thought I would like.I love all the gifts I receive it shows that the gentlemen is willing to do a little more.I never expect gifts but when I get them they are greatly appreciated and puts a big smile on my face.

You do not have to bring a gift to "impress" her.  A wish list is merely s suggestion that providers put on their sites to try and maximize the possibility of getting nice stuff.

Show up on time, be clean and respectful and have the proper donation.  Any lady who is not fully impressed with you by those simple actions is not worth worrying about...

Thanks Bostonguy57,

I think that is the best advise I could expect

You'd be suprised how many guys ask what to buy for gifts. We put those pages up because it's actually a rather frequently asked question. Plus, knowing what someone likes and dislikes can help you get a better feel for her personality (if that is important to you). Some of us would be just as happy if you tip or donate the money you'd have otherwise spent on a gift to your chosen lady's favorite charity.

I agree with you though, a lady worth her salt will never expect or require gifts; that said, gifts are always appreciated and remembered.
