Nice jacket!
Size: Large, Color: Dark Indigo Wash
I got this coat for my nephew because he has been begging for a similar one and he loves it! The sizing is dead on and the fabric is a little stuff so size up if you think you'll need to. Great quality, well made!

Cute denim Jacket
Size: X-Small, Color: Dark Indigo Wash
This Jacket is the cutest on my daughter! I caught it on sale which is a plus. Fits my daughter good with room to grow. It had a smell but it wasn’t bad enough to take off any stars.
