What you are asking. Is it basicaly 'can I get a fuck out of this'? If that is the real question, I think maybe you need a slightly different shop. As to what to wear - in either event, I should imagine smell clean, but not overpowered with aftershave and such, and clean comfortable clothes - by comfortable I dont mean out of the rag bag.
I myself have never been to such an establishment, but my ex did visit a couple of ladies in Antwerp. He thought he was paying for a threesome, but they made him kneel on the floor, lick their boots, and wank himself off. He didnt think he got his moneys worth - I thought it was priceless myself. He wasnt untraveled - he was a captain on a small coaster owned by a dutch company flying heaven knows what flag. And he was 'frugal' to an extreme.
