The popularity of bandeau and triangle bikinis can vary depending on current fashion trends and personal preferences. However, historically, triangle bikinis have been more popular due to their classic and versatile design that flatters many body types.

Ultimately, the popularity of each style can fluctuate, and both options continue to be widely worn and enjoyed by many. **
