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! 👌

Adorable toddler jacket
Size: 18 Months, Color: Stone Medium Wash, Size: 18 Months, Color: Stone Medium Wash
I love this little jean jacket! It's a really good quality denim, thick and weighted with a soft lining. I washed and dried it in the dryer without notable shrinkage, but the denim did fade slightly around the cuffs and seems (photos after washing). I like the look it gave though. It feels very durable and high quality for the price. It is an oversized fit. I got size 18 months and it runs large with a loose and long fit. It's very cute on my toddler though and goes with everything so a very versatile piece! I would say it's a medium to light weight/temp jacket great for spring, summer and fall. Overall, I would purchase again! I think I'm going to embroider some flowers on it, great base jacket for that!
