My first three Sorbettos were cotton and linen fabrics with darts added to the back and button fronts. For the polyester type fabrics, I really like the front tuck. The top is actually pretty easy to slip over the head even without a front opening or back slit.
Sorbetto #1 - Poly/cotton remnant from an underwear company
Sorbetto #2 - Linen with Venetian hemstitch
Sorbetto #3 - Double cloth reversible fabric from Wal-Mart
Sorbetto #4 - Poly woven fabric
Sorbetto #5 - Poly woven fabric
I never put this favorite pattern away. It's pinned to the bulletin board behind my sewing machine waiting for Sorbetto #6!
