Many people have heard me say “The skimpier, the better!”
That was my motto when I first got into my Emma Frost costume, later on, I branched out into more complex Cosplay but my heart belonged with skimpy ones.
Simple! The less pieces on a costume, the less likely something will go wrong. For example it could tear, fall off, impair your vision and movement, get left behind, break, be tugged and pull by an obnoxious child or generally cause some form of convention floor mayhem.
Consider my Vampirella vs. Arachne costume.
