I'm beginning the very long process of getting both arms sleeved in tattoos. I'm only at the shoulder-cap stage now, so undershirts are doing the job of covering my tattoos at work. However, soon I'll be starting the linework on the parts of my arms that an undershirt won't cover. I generally wear Lands' End dress shirts, and some of them, particularly the patterned shirts, are dark/sturdy/busy enough to cover things up. However, I'm looking for nice, reasonably priced white dress shirts that are thick enough to cover heavy tattoos. The tattoos show through Lands' End's white shirts. Thanks as always for your help!
