David Brooks Purple V Neck Sweater Size S/P

David Brooks Purple V Neck Sweater Tag says Size S/P. I’m not sure if this is a petite because of the P? I purchased a long time ago from a David Brooks Store but I don’t recall how the sizing was for the sweater. Please see my approximate measurements for help with fit. I wore this a bunch over the years so it shows wear including some pilling. Colors may be off because of lighting. I have a reversible petite skirt listed that I purchased with it that looks great with it!
