Absolutely worth buying!
Size: 6-9 Months, Color: Stone Light Wash
The cutest little basic for our little! I grabbed this for my 6 month old baby before a trip north that was expected to be cold. It's so cute and very warm!
I will definitely be grabbing a larger size when the weather gets cold again!
Also the price! 👌
