Stag party revellers often dress up in weird and wonderful costumes to help the groom-to-be celebrate.
However, this month there is extra incentive with Halloween only a few weeks away.
Shops are packed full of outfits that could be used to make a stag weekend more fun, while traditional stag party destinations like Dublin are hosting a range of events to celebrate the holiday.
Beginning tomorrow (October 15th), the Fright Night Bus will take those brave enough to travel to the City of the Dead on a haunted journey.
The black vintage vehicle will transport guests to the city's spookiest graveyard with a Victorian gravedigger to keep them on the right path.
Their host will tell stories by lantern light and ensure the stag party has a ghoulish time - whether they dress up or not.
Those who do not fancy hanging around graveyards at night might rather head to the GAA Museum, which is holding a number of Halloween-inspired events in the run up to October 31st.
