かわわい女の子しか雇わないって英語でなんて言うの？

The word "attractive" has many uses and is a way to talk about people without it being seen as rude or degrading. I hope that this helps :)

In some retail outlets, the employers may have made a decision to employ attrtactive women for a reason. For example, a bar may prefer attractive female employees in order to attract male customers. Anyway, the example sentence is a casual comment about such employment practice.

When you are talking about a certain store saying, "They only hire cute girls/ pretty girls/ attractive girls." or "They hire based on looks." will let the other person know that this company hires based on looks.

They only employ girls who look attractive. This sentence looks to say that a specific place only hires people who are in actual fact beautiful. They only hire girls who they think are beautiful. This is a statement about the mindset of the store owners. In this sentence the girls may not be beautiful but we are saying that the people who are hiring 'think' that the girls are beautiful. Employ is another word for hiring.

When you're talking about a store that only employs beautiful women/girls; then you can say: -they only hire beautiful women -they only hire cute girls

The first phrase is the simplest way to say this. 'Looks' means 'physical traits that are attractive.'
