I recently purchased this jacket online in the rose color and it is beautiful! i usually wear an xs in retailer but purchased this in size s after trying on the grey color at the store. there was no xs to try for comparison but the s fit well and leaves room for light layers underneath. the only reason i rated it as "runs small" is that xs is my usual size so this may be true to size for most. i also wanted the option of zipping with layers underneath. the sleeves are long but can be rolled
