Adjusting a Neck that's too wide. Is your shirt falling off your shoulders?

So your neck is too wide on your sleeveless top/dress, and consequently the shoulders keep slipping off.  Here's a quick adjustment to get a good shoulder fit.   All fitting starts from the shoulder so getting this correct will allow you to draft with confidence.  This example is on a sleeveless top, however, this applies to garments with sleeves as well, except in that case you would also make some adjustments to the cap.  I'll save that for another tutorial.
