Some offices have the tradition of celebrating a bride-to-be with an office bridal shower. These resemble your usual shower typically put on by friends and family, except it's planned by your office mates and the guest list is limited to your female co-workers. Sometimes the women spearheading the shower will try and surprise the bride and they secretly send invitations to all female employees and include registry information. The party is typically held during lunchtime and likely takes place in a big conference room. More often than not, cake is involved.
