你给的句子中，似乎有拼写错误。

该句的正常表达应该是这样：

1. She gazed, and her hands overlapped to her breast. （并列句）

2. She gazed, her hands overlapping to her breast. （简单句，书面语）

3. * She gazing, her hands overlapped to her breast.（语法不错，逻辑不通，不予采纳）

【说明】该句的信息重心应该在She gazed（她凝视着）上； 而her hands overlapped to her breast 是次要信息，可以用“分词独立主格结构”来表示，作伴随状语。所以，句2正确，句3存在逻辑错误。
