Talbot's Embroidered Floral Peplum Blouse says Size 6 but really 4/XS

Beautiful blue floral embroidery decorates this white cotton fitted blouse with a hidden zipper on the side. The peplum has a scalloped hem. An exceptionally pretty and feminine top. Runs small, think size 4 or XS. Length back collar to peplum is 14.5", to hem is 26 in. Flat measures: waist :16.5", hem 22", shoulders 14.5" (shoulders seem to be the problem for those who have tried it on.) Exceptional pre-owned condition.
