Review (5/5): My favorite
Many patterned bouffants can be ~$20 a piece, so I decided to start with a cheaper multipack of plainer bouffants. I bought a 6-pack from this brand, and really like them. They are very slim-fitting, breathable, and contain my hair perfectly all the way around. Only one of them unraveled a bit in one of its first washes, but otherwise they have all held together.
I later tried a different brand, a more common "poofy-er" model, and went right back to these instead. I really like these bouffants, and will continue to wear them.
