During a celebratory night out then it is absolutely essential that you have a shot glass to hand at all times to really enjoy the evening in a fashion like no other. You should be able to keep this on you at all times thanks to the pink beaded necklace which is attached and it will be clear that it is a predominantly female zone thanks to the 'girls night out' writing.
There are also shot glasses with similar designs for the bride to be and those girls who are top tottie.
