To be fair, given the size of many of the clothing items there, making one should count as "mass production"

Torrid is a chain store owned by Hot Topic. They strive to provide fashionable clothes for plus-size teenagers, wearing sizes from 12 to 26 and fashionable options that "empower" women. A plethora of the clothing sold may be considered "hard to find," as they claim that much of their clothing is not mass-produced.
