LacosteMen's 100% Cotton Regular Fit Crew Neck T-Shirt, 3-Pack

Hola, quisiera saber cuál es la diferencia entre el color negro y el Chineblack?

Are the shirts slim fit and for an 5'6 guy how would a xs fit

whats the size chart for this?

Is the alligator logo embroidered like pictured on your advertisement?
