Too large for narrow shoulders
There’s nothing wrong with it as far as I can tell except that it’s too large. The chest-based measurements are not really what determines the fit here, so if you have very narrow shoulders and a thin frame—regardless of how big your chest is— I’d suggest finding a similar product that comes in different sizes. On the tightest setting, I can still fit my hand easily under the strap, and I have a 33”-ish chest but very small, thin shoulders.<br /><br />Fwiw, these posture devices do really help.
