I like Old Navy too but I can't always get a good consistent fit from them.Sometimes there stuff runs small and sometimes big. I am an all cotton gal,and it doesn't get much better then them for comfy t shirts and pajama pants though.
Sistermadly,I adore my Birkenstocks.As for being ugly,I have a pair of slip on Birk clogs that I get more compliments on than any other pair of shoes. By the way,I am all about my DELL computer.
