So Pretty Shower caps are generously oversized as a standard fit.   (Check out the "About my Shower Caps" page for a photo example).

But sometimes even this is not enough!!  Now a shower cap is available that is glamourous to wear rather than resorting to a plastic shopping bag!

This XL size is recommended for extremely long (eg lower back) / unusually thick hair, or to accommodate dreadlocks to middle back. 

The ribbon bow is wider ribbon to complete the larger look :)
