Knowing your body measurements is super handy! Before you buy a costume, movie halloween costumes I HIGHLY recommend you measure yourself to know your body stats. If you love a good bargain on our product, you’ve come to the right place.

Save the measurements down on paper or on your computer for future reference; these numbers will be handy because every site has their own different sizes.
