I don't shop a lot, but when the Lands' End catalog came this week, there were a couple of things I found potentially useful.
One is a pair of these in boring, conservative gray for yardwork. Should I have bought lime green?
The other is three of these, since I've worn the daylights out of the similar v-necks I bought a couple of years ago. They're good tees, and buying three, they cost $7 each.
These tees are cut reasonably, so I needn't worry about bra straps or underarm gaps.
