Ok, so yes, it is true that the top part where the sleeves are can be snug a little, especially if you work out, but overall i found the top to run true to my regular size (i only tried on the 0, didn't try bigger). the length was great for me being short, i didn't think i need the petite (i usually do for pants and skirts/dresses, tops on and off). the look of the shirt is also classic, flowy and it looked great with e half tuck. the embroidery is also nice though one part of it seemed loose. a
