Perhaps the appeal for some is that it makes your shoulders appear broader and your arms look smaller by contrast, like a cartoon of a human woman form. If we’re to take the Frankie Shop styling literally, and wear the shirt tucked into a voluminous pair of pants, cinched tight with a belt, this shirt is excellent in reimagining your figure as a perfectly symmetrical infinity symbol. In truth, all of the women I’ve seen it on are already quite slim, and the exaggerated proportions of the muscle tee call attention to said slimness. I haven’t seen it modelled on plus-sized women, and the Frankie Shop’s largest size is only six inches wider than its smallest, so I don’t think that this is a style made with actual curves in mind — instead, it fakes or emphasizes them, with the shoulder pads acting as a wink. They’re obvious: It doesn’t actually make it look like you have broad shoulders.
