In addition to producing their own records, Broken Doll run their own fashion label and apparel shop "Broken Doll." They are also involved in stage costume design, production, fashion modeling, and hosting their own events. Their DIY spirit as an indie rock band is reminiscent of the Sex Pistols, the punk icons in the 70's, who merged unconventional fashion and rock music. Broken Dolls follow their path by being a subculture transmitting girls vocal rock band.

Their one-of-a kind fashion has been reaching the world through Facebook and recognized worldwide as one of the signature styles of "Tokyo Harajuku Kawaii Fashion" in recent years. Their fashion has been hugely influential on Harajuku street kids as many entertainers and street models are sporting Broken Doll items in fashion magazine and famous TV programs.

They have collaborated with Akihiro Nanba, bassist/vocalist of the Japanese melodic punk icons Hi-STANDARD, to design/produce T-shirts and other apparel items. This indicates the band's wide-ranging interaction with various artists. They have been taking variety of approaches to exude their presence to Japanese street kids.
