Whether Jo Malone Bay & Sea Salt Perfume is suitable for wedding banquets depends mainly on personal preference, the theme of the wedding banquet, and the formality of the occasion. Here are some suggestions:

1. Jo Malone Bay is a fresh, natural fragrance whose main fragrance ingredient is bay leaf. It has a fresh, herbal scent that's perfect for spring, summer, and daytime use. If the wedding reception is outdoors or held in a more relaxed and natural place, this fragrance may be more suitable.

2. Sea salt perfume has a unique salt water fragrance, giving people a soft and warm feeling. It tends to be suitable for warmer, beachy or casual wedding occasions. If the theme of the wedding reception is beach style or the wedding reception venue is more relaxed and free, then this fragrance may be more suitable.

However, for wedding banquets, it is generally recommended to choose a perfume that is milder, longer-lasting, and not too irritating. In addition, when choosing perfume, be careful not to interfere with other people's perfumes to avoid conflicting smells.

The most important thing is that personal preference and self-confidence are the most important. If you love these two fragrances and wear them with confidence, you'll look unique no matter the occasion.
