prekrasnaya or krasivaya?
I just flicked back and forth in my dictionary and it's a bit confusing. The entry for prekrasnaya says it can be used for a zhenshina, but the entry for beautiful says it should be translated as prekrasnaya for a day (weather) or experience, and as krasivaya for a woman or place.

My memory tells me that women are much more often krasivaya than prekrasnaya.
