I love the Besso jelly bags. Very cute for spring. It's versatile - can be worn going out to the beach, or can be used to carry books or diapers. It's made of rubber, so it's washable, and more durable than plastic or vinyl because it doesn't tear. While nothing beats a Birkin, it's a fun alternative for a decent price. I think the rubber makes it playful. Besides, I don't immediately think of 'Birkin' when I see the bag. They have their similarities in shape, but ultimately, they're different.
Head to your local TJ Maxx - large sizes are only $69.99 and medium sizes are $59.99. It's a steal at that price. I saw it in black, ivory, light yellow, and light blue. I think it would make a great gift item for the holidays!
