Bodypeace Bamboo clothing is made from a medium weight bamboo fabric blend of 92% Bamboo and 8% Elastane which means that it has some stretch to it and won't lose it's shape after washing.
If you like a loose fit then you can probably go up a size.

Small:       8-10
Medium:  12- 14
Large:     14 -16
XL:        16-18
Extra:       20+

To care for your Bamboo clothing wash by hand in cool water or inside a laundry bag on a gentle cycle.
Enjoy!
