After receiving my husbands shirt, we realized it was too large. He was not a Large. K of C 4th degree coming up at week end, I never thought we'd get the smaller shirt in time. Don't know how they did it, but we did receive the shirt, it is perfect size, lightweight to go under a tux, well made and great. Our son tried the first shirt and it fit! So, no returns. The customer service we received from this PerfectTux company was unprecedented! My highest compliments. Thank you. P.s. They were perfect for the occasion and comfortable under the tux.
