I was tired of wearing a classic, crinkly, mushroom-shaped shower cap over my curly hair, so I bought one of these instead! It's lovely, comfortable, pretty.
The only challenge I have is that the one-size-fits all means the cap has to accommodate long hair AND short hair. I have very, very short hair and a relatively small head (in terms of cap size), so between the combination of those circumstances, there's a bunch of excess space inside the top of the cap and the base doesn't fit quite as snugly as I'd wish (some short tendrils sneak out the bottom and tend to get damp).
Still, it keeps the rest of my hair dry and looks really adorable! If the seller started to sell a “short hair” and a “long hair” version, I'd truly be in heaven!!
