A little girl is invited to a birthday/tea party with a lot of rich girls. Her mom can not afford a new dress so she buys fabric & makes her one. This is a very old movie I watched it about 15-20 years ago. She had a dog that ruined the tea party. She saved her money in a jar that she hid in the barn/garage. The other girls were mean to her because she was poor. Please someone help me figure out what this movie was called.
