More wedding wear question-hose?

If I may ask a further “pantyhose” question without hijacking the thread, I am going to a wedding this weekend where the ceremony will be outdoors in weather which looks to be about 65 (at best) and sunny during the ceremony. We are then going into a tent with heaters, and the temp is supposed to drop into the 40’s by wedding reception’s conclusion. While I would like to get away without pantyhose, I think I might need to wear them because of the cool weather.

I bought a pair of Hanes Ultra Sheer size A/B, and they are just too big for my lower calves and ankles. I have pretty good legs because I work out regularly. Anyone know of a brand which would likely fit a smaller leg?
