Bathing suits are often a source of contention with pear shapes. It is hard to find a suit that fits well for the top and bottom portion for the body. This is even more complicated when you are also plus-sized.
Someone with this body type would look best in a tankini. Tankinis offer the coverage of a one-piece suit with the advantage of purchasing two pieces in different sizes to accommodate your body shape.
Pear shapes should look for bold color on top and darker colors on the bottom. The idea for this shape is to draw attention upward.
