In addition to addressing the toxicity of a mass-produced object like the T-Shirt, the image makes a claim about toxicity in on the scale of the domestic as well as personal space. The interpellation of the individual reader is quite clear in the sub-headline. Here, the clothing closet is invoked as an intimate but also opaque space, where toxicity is not expected to be found. This could be contrasted with domestic spaces where toxicity is expected and contained, for example in the garden shack, a bathroom cabinet, or the kitchen sink, where clearly labeled chemical products live. The "closeted" toxicity presented in the image also points to feelings of guilt and hiding from the toxic dimension of one's fashion.
One of the many powerful dimensions of this image is portraying the presence of toxicity in everyday products. Fashion could point to many different kinds of clothing, but I think the choice of the T-Shirt is purposeful. Like the mass media addressed in the title chosen for the image, the T-Shirt is aimed at a mass audience. While the presented item is a "regular" or "unisex" version, the pink color in the background could indeed communicate a more feminized dimension of fashion production. In addition to being a "basic", mundane object, the T-Shirt is also most closely situated to the skin, which emphasizes the unsettling effect of the bubbling green toxic mess.
