Because girls like dinosaurs and rockets too.
Mercury13 is a small family run business which started after I found it very difficult to buy cool clothes for our daughter with dinosaur and space themes on.
I (and my daughter!) didn't think that dinosaurs and space should be for boys only, so I started making her clothes. After getting lots of remarks when we went out about her dino dresses I decided to start selling them and Mercury13 was born.
Now our collection has grown to diggers, football, pirates, race cars and cowboys!
