Start with a personalized first message. A line that references something specific in her profile - a city she travels to, an interest she listed - signals that you actually read it, rather than sending the same opener to twenty women at once. Honest, relevant answers to her questions matter more than clever ones; accomplished women can tell the difference quickly.
A short video call before your first meeting is common practice and worth suggesting yourself rather than waiting to be asked. It confirms you are who your profile says you are, and it gives both of you a lower-stakes way to check for chemistry before booking a table.
On dress code: a good rule is to dress one notch above what the venue requires. A blazer with dark trousers works for most upscale restaurants without tipping into full formal wear, which can read as trying too hard on what is not a business meeting. If your first date includes travel, our guide to luxury travel etiquette covers packing, hotel manners and privacy on the road in more depth.
Two habits matter more than any single gesture. First, never ask for photos beyond what her profile already shows - if she has shared five images publicly, that is what she is comfortable with; anything beyond that is a request she did not agree to. Second, if an arrangement runs its course, say so directly. A short, respectful message closing things out is worth more than silence, and the community is small enough that word travels.
