The word "wreathlike" describes an object or a decoration that resembles a wreath. There are several synonyms that can be used instead of "wreathlike", such as circular, rounded, ring-shaped, looped, garlanded, and circlet. Circular refers to a shape that is perfectly round, while ring-shaped and rounded refer to a shape that is more oval than circular. Loop-shaped objects have a round shape with a gap in the middle, and circlets are small circular bands worn as ornaments on the head. Garlands, on the other hand, are more flexible and can be made of leaves, flowers, or various other materials. All these words can be used in place of "wreathlike" depending on the specific context.
