Which element may add unnecessary bulk to a corsage?

Heavy embellishments can indeed add unnecessary bulk to a corsage. The purpose of a corsage is to be elegant and to complement the attire of the wearer, and excessive weight or size can detract from that elegance. Bulky embellishments, such as large sequins, beads, or heavy fabric, can overpower the delicate flowers and the overall design, making the corsage less aesthetically pleasing and harder to wear.

In contrast, lightweight flowers are essential for ease of wear and to maintain the corsage's graceful appearance. Color-matching ribbons serve to enhance the look without adding substantial volume, while delicate foliage is often used to add texture and interest without adding bulk. This balance is crucial in ensuring that the corsage remains comfortable and visually appealing.
