Hello Marcy, I'll write in english because i only know portuguese...

I've been working from home for about 8 years from now, and I dare to say working on pijamas is the best thing you can do and its not even close... my most productive mornings where in underware and t-shirt... nice coffe and in the zone...

This no pijamas is just a cliche in my humble opinion...

Cheers, and nice to meet you!
