So pretty!  Vintage Alex Colman button back top in turquoise with gold roses that have either tan or orange outlines.   the torso of the top is lined with a silky fabric, the sleeves are not lined.   Bracelet length sleeves and rounded slits on each side.   The top button has been replaced with one that looks close to the originals.   There is also a VERY tiny dot on the back near the bottom.   No size tag, so please be sure to check the measurements carefully.   All measurements have been taken with the top laying flat, so may need t be doubled.
