One of our favourite characters in Finding Nemo, apart from Nemo of course :) was Bruce the shark! He lead the Fish friendly shark support group. We love the idea of fish friendly sharks so ours are made out of fabric!
The bottoms have a shark print on them, in a rib jersey for a snug comfy fit. The T-shirt is also made of Rib fabric so both items keep their shape. If you little one prefers a tighter fit PJ at night, then this style is definitely for them.
The top would also look cool with some denim jeans or shorts
