Collars is a dating retreat experiment for those in "e;collared"e; lines of work (ex: blue collar, white collar, etc.). One qualified person from each field is selected for each group of ages no more than 20 years apart, and in a spin-the-bottle-type fashion, couples are formed to enter private suites for their overnight dates until all options are exhausted. At the end of the retreat, participants are asked to submit who they are interested in pursuing. If any of the participants match, they're each informed via email, sharing both parties' basic contact information and allowing them to continue how they see fit.
