Translation of knickers in Spanish

I saw that you agreed to work for the dictionary. thanks for that. The payment is 0.04US$ per translation. If you skip the word for any reason, it would not count. Could we try out 100 translations as a trial?
I am a computer scientist and I also have a small restaurant with my younger sister (she is also already 53). You can come and visit, I will buy you a drink and we could chat a little.
I hope there were not too many mistakes here. I have learned Spanish not a long time ago and I am still very insecure! Tell me please, where do you come from and what you do?
