j. crew has two spring jackets in tall sizes T2-T14. the tall solid tulip jacket is pretty cute, but it has that intentional shrunken look that irritates me. (if i want a shrunken looking jacket, i will wear a regular size jacket. oh, well.) but the tulip sleeves are very cute. i would be very tempted if it were a bit longer.
then there is the tall linen-cotton casa rossa jacket. it has a more streamlined fit than your average linen jacket. i might be interested if it came in better colors. it comes in yellow, orange, and white. i prefer boring basic neutrals.
but, it is good to have a couple tall jacket options. i will have to look around and see what else is out there. my favorite wool herringbone jacket is not very spring/summer.
