Took a chance buying a off brand slim shirt- I was happy with the material quality however the shirt dimensions seemed unbalanced between the torso and the arm opening. Tighter than I expected around the upper torso as and looser in the lower abdomen - with arm openings fitting fairly loose for a small. My arms are slightly larger than normal and the sleeves were loose. Compared to other slim fit shirts I have from Lucky, DKNY etc. this shirts dimensions seemed off. Was surprised to see so many 5 star reviews as I have not owned another slim fit shirt with a fit similar to this one- also the neck cut was a little odd. I completely understand everyone has a different shape and size overall- but this ones fit seemed pretty far off the norm.
