The brand runs quite small.  I ordered 3 sizes up and it fits great.  This dress is so pretty on.  I have an hour glass shape and it accents all the right places without clinging to the places I don't want emphasized.  People have given me many compliments on it.  It makes me feel pretty and reminds me of bygone days.  The price is excellent.  The hand of the fabric is lovely.  Highly recommend Lindy Bop
