For size:
I have the T-shirts initially ordered in M, because M has me actually getting fit. Unfortunately, however, was not applicable here. I find that the product precipitates a little smaller than normal. Anyone not wearing his skintight other tshirts, may well remain at the same size here.
For Service:
The shipping is very fast. The refund of the monies paid in exchange took a little longer, but it was handled as expected.
Conclusion:
I think the T-shirt super and can recommend it to anyone who is looking for plain black T-shirt with V-neck.
