Doll (muñeca) you may know. Young girls often have a “doll´s house.
However, there are some expressions that use the word. Consider these:
You “are a doll” to help me. This is a way of saying thank you for the help you have been given. Perhaps in Spanish you may say “eres un ángel, o gracias a ayudarme”.
Sometimes ladies “doll themselves up” (emperifollarse, emperejilarse), that is wearing fancy clothes and makeup because they would like to be seen as attractive.
