My tank tops arrived yesterday, and I'm really glad I bought two -- just one is slightly see through, but when I layer them, it looks pretty good
! I'm satisfied. I'm wondering if I should try sewing the two shirts together so I don't have to worry about one riding up or whatever, but I don't know if that'd work.
And dying the binder is a really excellent idea -- I just might have to procure some dye and give it a shot! Thank you so very much to all of you who responded, you were a great help!
