If you have trouble fitting the bust of your bodice or blouse, you may need a Full Bust Adjustment.
The FBA adds a bit of room through the bust, without making the entire bodice larger.
Most commercial patterns are made for a "B" cup body. If you're larger or smaller than that, your bodice may pull across the bust (if you're a "C" or larger) or gap (if your bust is an "A"). Your armhole may not fit properly, or you may have drape lines from the shoulder.
While I have a page explaining the FBA, it can be a bit confusing. I hope this video helps!
