Paul Smith SS 12

This tailored shirt by Paul Smith in his SS collection shows a perfect example of  a tuck on the cuff of the sleeve. The fabric is folded back on it's self for both the purpose of shortening it's length and for visual purposes as it adds to the tailored look making it look more finished. For this reason, tucks are often found along the hem of garments.
