Temperature Difference

The temperature difference between morning/evening and daytime has become about 10 degrees. It finally feels like autumn weather, but I don't know what to wear for fall... Last year, I feel like it was summer until it snowed, so fall... I find myself thinking, 'I'll just take out my long sleeves for now.' It's supposed to be around 23 degrees tomorrow in my hometown, but it's supposed to be sunny, so it might be warm for the temperature. Good night~😪
