The pants elastic is a very simple design that is very useful and has a great affect. It is made of two pieces of green elastic twirled around each other with a hook on either end.
The lackies go around half way between the top and ankle of your booty.
Then you let the bottom off your DCPU trousers hang as far below the lackies as possible.
When this is done grab the lackies through your trousers and tuck all the excess material that hangs below the lackies up inside your trousers.
When this is done place the fold of the trousers back on the boot.
Comes as pair.
