I gave this as a birthday present to my wonderful neighbor... an avid gardener...she liked it!  The material seems to have a little more substance than regular tee shirts and, with the pretty, bright pink I told her she won't be able to hide in the garden anymore.
She did say that she'd feel more comfortable in the next size up and will be exchanging it (my fault for underestimating!).
BTW Amazon had sent me an e-mail saying delivery would be delayed up to 2 days but it arrived today, as originally promised!  Well done, ThisWear.
