360C: A perfect day at the shore

I’m looking for an old children’s book that my mom used to read to me but I can’t remember the title. It was about a mother and a young daughter who spent the day together getting ice cream and going to the beach. The beach was a New England looking type of beach, the illustrations were pastel in nature, maybe watercolors. I feel like it was called something like The Perfect Day or A Day at the Shore but those titles aren’t turning up results. I would have read it in the 80s and early 90s and it was not brand new then. It is not Beach Day, Day at the Seashore or The Seashore Book
