Hair Bun at the Chinese Teahouse

Most of the time, I wear my hair undone because it takes too much time to do my hair. It´s just too straight and due to my pregnancy, I have so many babyhair at the hairline hence it´s even more difficult to style my hair. But this time, I managed to put it up in a bun, it´s not perfect but I love it. Even though I feel most comfortable when it´s undone. What do you think? 
And yes, my baby tries to walk, I´m so happy! But as he isn´t able to walk alone yet, it can be soo exhausting holding his hands all the time. Sooner or later, I will definitely get a backache... :-)
