So I had this idea to get the girls robes which I think are fairly common. I personally hate terricloth robes so I was thinking satin robes would be nice. If the girls wanted to use them when we are all getting ready that would be fun and then it is a sexy/feminine fun gift after. No monograms or "bridesmaid" plastered anywhere. The most reasonable ones I found happen to be a two piece set with a chemise under it. So now it went from just a robe to essentially buying them lingerie and a matching robe. Is this weird? I put a picture below. I'd get them a different color (black or red I think are the most fun) but this showed the set best.
I should mention that all but one of my girls are FAR from prudish. And the one who is, is only because of her religious beliefs of no pre-marital sex (so she's not really a prude so much as resisting temptation). But she is getting married 4 weeks before I am so will be in newlywed phase after 25 years of waiting!
