My guest list is just about at its limit but I left a few slots for work friends. My job changes over often so I waited until closer to the wedding to see which friends actually stayed in the area and in touch. There is a group of girls I hang out with from work, so I would like to invite them, but won't have room if all of their husbands come. Is there a polite way to invite the as a girls night, or should I just say they don't make the cut? Also, there are several people in the department I do not see outside of work, so I thought it was fair to only invite the specific girls. Advice, please!
