After the armhole has been cut down a bit, the bust drops a fraction. In this case, Sheree is still well-supported.

If the bust drops too much during your fitting, readjust the shoulder seams tighter.

NOTE: I accidentally cut the armhole too large during this fitting. In the final making of the gown, I had to piece the armhole to make it smaller. Try not to make that mistake. It IS easy to do, though.
