I had my bachelorette party in February in DC - so it was going to be cold.  I wanted to wear a short and sexy dress but didn't want my legs to freeze, so I purchased these thigh-high boots.  They come up super high so I had to pull the dress up a bit but they did the job and fit my calves which is usually never the case with knee-high or thigh-high boots.  They were comfortable enough to dance in all night and I look forward to wearing them again.
