They turned out exactly as we had hoped and we looked good even when we didn't bowl well. The printing was perfect and you can only see 9 pins on the shirt(the 5 pin hidden behind the headpin) which worked for us as we bowled in a 9 pin No-Tap league.

The shirt I ordered was too small. I contacted Zazzle and they replaced it with a larger size. Very happy.

The quality of the shirts is top notch, comfortable, well fitting, the material is great. The shirts are well made and we were proud to wear them. The colors were as bright, clear and pure as advertised, easily read, not only by us, but by family and friends who saw us while we were wearing them, immediately smiled, congratulated us, asked more about our big day 50 years ago.. The printing showed up great in pictures, and we have attached a copy of us wearing them.
