Why do we women take soooo much longer to get dressed than men?

I read that on average it takes 30 minutes to an hour for a woman to get dressed. It takes guys on average between 5 and 15 minutes. I know this is certainly true when my boyfriend and I get dressed. I also read that we women spend 17 minutes picking out an outfit, but only about 13 for a guy. So, I just wondered if we are spending 17 minutes picking out an outfit and 30 minutes to an hour to get dressed, it seems that over time this would add up to a significant portion. I also read the older that you get the less time (based on people in their 60s). Why does such a huge gender difference exist in the years before the 60's. What are some factors that may cause this?
