Sturdy carpenter jeans in thick dark wash cotton denim, by Korean kids brand Ellymolly.
These have all the details of an adult workwear pant - belt loops, front panels, loop for a (tiny) paintbrush or a (toy) hammer - but scaled down with a kid-friendly elasticated waist for easy dressing and room to grow.
Beautiful quality construction in durable denim.
These run big, especially in the waist. Please refer to the measurement tab!
