If you mean “a good-quality escort”, here’s what people usually mean—at a high level, focused on companionship and professionalism:

•Professional & discreet – respects privacy, boundaries, and confidentiality.

•Great communication – easy to talk to, attentive, adapts to different personalities and settings.

•Polished appearance – well-groomed, stylish, appropriate for the occasion.

•Reliable – punctual, organized, and keeps commitments.

•Emotional intelligence – respectful, empathetic, reads the room well.

•Pleasant presence – confident, calm, and able to make time together feel natural and comfortable.

In short, good quality = trust, respect, and a genuinely enjoyable presence, not just looks.

If you want this described more formally, more casually, or in another language, say the word.
