I did the same thing last year, I thought it worked very well.
Am I going to be the only one wearing a wide brimmed sun hat? I don't wear ballcaps because they don't suit me but I also don't see how a ballcap protects you from the sun...I have to protect the back of my neck because I've burnt it so badly over the years. Slightly OT: The other thing I'm going to try is a sheer gauzy scarf thingy that I can wear over my shoulders when I feel the need so I can wear tank tops - t-shirts give me a tan line and make my shoulders look too wide- and hopefully they will catch a breeze. We'll see how that turns out, I'll probably end up leaving them in my bag
This will be the first time my hair is below my shoulders and can be worn in a ponytail, but I think I will wear a headband to keep it out of my face when I'm not wearing my hat ( that drives me nuts)
