Blue Swing Tunic Button Front Sweater Cardigan Size S/M

This gorgeous blue swing tunic button front sweater cardigan is in very good preowned condition. No major flaws. Looks like a periwinkle blue to me. The brand, fabric and size tags have all been removed so I don’t know the brand, the material or the sizing however the measurements seem to indicate this would best fit a size small to medium. Has snap front closures and adorable 3/4 length bell sleeves. Approximate measurements laying flat: 26.5” length 17” bust stretching to at least 20” 20.5” sleeve length
