Translation of undershirt in Spanish

I will built a function that will do all lowercase but meanwhile, I would be happy if it could be rewritten to lower case... Is it possible for you? They should all be lowercase, I did it inadvertently.
As mentioned in our conversation, I will send a more detailed description about all the other exercises. As indicated previously, I believe in your technical skills and in your talent.
We all are too busy these days, no one has time for leisure. It is all about money... Anyway, if you have any question or you want to know about my country, you can write me a message on Vocabulix.
