About Lil Monster Overalls

Lil Monster Overalls (Lil Monster) is a private Chinese denim brand owned and operated by Dong, who is a good friend of Kai and also a big fan of Iron Boots. Dong is a big denimhead since 2006, and obviously he has hundreds of denims (unfortunately his collection is stopped by his wife many years ago). He was a breeder (hence the brand name and logo), and he decided to start Lil Monster in 2019.

Lil Monster is run all by himself. He is a designer and he designed every single Lil Monster denim, which is also what he feels most proud of. You will find a lot of interesting design details in every single denim of Lil Monster.

About Denim:

Lil Monster Overalls X Iron Boots Denim (2022) is a collaboration happened at 2022 between Lil Monster Overalls and Iron Boots, so we also call it "Iron Monster". If you pay attention to the packaging and leather patch, you will realize that this is a story about how 2 brothers (Todd & Pipi) jail breaks together. That's why there are a lot of orange color elements on this denim. Since this is a collaboration with Iron Boots, we have used brown S.B. Foot leather on this denim, together with a "brogue cap toe" style pocket stripes!
