Can a lady wear jeans to the beach?

Is it really appropriate for a woman to wear jeans to the beach? Won't she feel too hot and uncomfortable with the heavy fabric in the sweltering sun? Are there any beach fashion norms that dictate against jeans, especially for females? Do beachgoers typically opt for lighter, more breathable clothing when lounging in the SAND and sun? Additionally, aren't jeans more suited for everyday wear, rather than leisurely activities at the seaside? What factors should one consider when deciding what to wear to the beach, and do jeans fit into that equation?
