Petite, seven companions and a note on measurement

Listed from shortest to tallest, each with the one detail guests tend to remember.

• Tina, 158 cm: records, vintage clothes she alters herself and a gin with the correct garnish in Notting Hill.
• Jasmin, 160 cm: perfume, rum and salsa, with a late start preferred.
• Rosa, 160 cm: chestnut curls, home baking and crates of second-hand vinyl.
• Lea, 161 cm: new plays on Sloane Square and a decorator's eye for any room.
• Sonya, 162 cm: a dancer's poise, a quiet bar at The Milestone and the ballet when it is in town.
• Lucy, 163 cm: museum lates, careful espresso and the planets above SW7.
• Tiffany, 169 cm: design hotels, champagne at Blakes and a habit of straightening picture frames.

Several of the seven carry flat shoes for the walk and change at the door, so if your evening includes a stroll from the museums to a restaurant on the Fulham Road, say so when you write. It changes what she brings, never whether she comes. For black tie, mention the dress code in your first message so that she has time to choose accordingly.

Smaller rooms show this grouping at its best: a basement cocktail bar, the clubby bar of a townhouse hotel, a record shop before the shutters come down. Sonya and Lucy prefer the calm of a hotel lounge. Jasmin, Tina and Rosa lean towards somewhere with music, and Lea and Tiffany want a room with good design in it. For guests who would rather not go out at all, a hotel visit in SW7 or W8 keeps the whole evening under one roof.

Petite describes build alone, so these women appear across the hair wing: Lea with auburn and red, the other six with the brunettes. Rosa is also among the curvaceous, Lucy among the slender, and Sonya and Tina among the toned and athletic.

The fee is the same as for every companion in the catalogue, from £250 an hour. None of the seven lives in SW7: Jasmin and Tiffany come from Soho, Tina from Covent Garden, Rosa from Marylebone, Lucy from Pimlico, and Lea and Sonya from Belgravia and Knightsbridge, the two closest to the museums. That makes no difference to the price, because the fee already allows for her journey anywhere across Zones 1 and 2.

Write with a name, the hour and your hotel. On WhatsApp the desk will verify your full name and your room, and her arrival time follows as soon as the deposit, 25 percent of the fee, has come through from your bank.
