An escort agency will never ask you to be thin, as not all clients love thin women. That is not the case. They will ask you to take care of your appearance, whether you are a curvy person or taller or have short or long hair. That means you must always have a nice manicure and pedicure, take care of your skin, go to salons for facial and body massages, etc. That is what proper care means for agencies, not the number of kilos their companions have, as clients do not care about that.
