First of all, I think if your husband is willing to have sheep, HECK YES you want some sheep! And can I have a pony too? Oh, wait, what were we talking about?
I thought that the video was pretty cool. At first I was a little worried she didn't include laundering the dress, but then later she said she did. Whew! I think part of the program I wouldn't like is that you only have one of the thing. I wear a uniform to work (scrubs) and I don't mind it at all. But I have like 10 pairs. I'd be pretty sad if I had to do laundry every day.
I think it's actually kind of nice not worrying "what am I going to wear to work today?" When I was in vet school and my internship, we had to wear "professional clothes" and a labcoat. First, I think it's ridiculous for vets to have to wear nice clothing to work, hello, it's going to get peed and pooped on, etc. Second, I had trouble affording an entire wardrobe. And third, I had problems with fit. A lot of pants are getting lower waisted, and even nice shirts are getting more cropped, and I am tall. I was having trouble keeping my midsection covered, especially when bending over to do physical exams. It just doesn't look professional to have your lower back exposed! So I hear her on the making your own clothes to fit your own body thing. I try to do that with my knitting, although it doesn't always turn out how I planned!
