Morphsuits don't need explaining, the pictures say it all. You can see through them and drink through them...not that we'd condone that. So if you've got a party, stag or festival... What size of Morphsuit do I need? -------------------------------------- As Morphsuits are made of stretchy Lycra we have found that one size pretty much fits all but for the perfect fit please follow this simple guide. If you are under 5'4 go for a Medium. If you are taller than 5'4 but less 5'10 choose an L. If you are taller than 5'10 but less that 6'3 choose an XL. If you are very very tall (taller than 6'3) then take an XXL. Simples.
