Sometimes the simplest pleasures are the best. So here we have Susie, barefoot, dressed in just black yoga pants and a black crop-top, having a lovely play in the mudbanks.
Part way through the scene, once her initial outfit is covered in mud, she puts a clean light running jacket on over her mud-drenched crop-top, and then covers that in mud too.
Kneeling, sitting, sliding, rolling, gradually she drenches her entire outfit in soft, semi-liquid clay, and just keeps playing until she is totally covered in mud. Mmmm, squelchy!
