Let's face it: not a whole lot actually rhymes with the word modest. There are plenty of near rhymes but only a handful of true rhymes, none of which are really any better than the cringe-worthy slogan, "Modest is Hottest." The good news is that we don't have to have a cutesy slogan for church activities! Strange, but true.
Alliteration is also optional.
Still, some of modest's rhymes are fun to stick in that blank. Like bodice. "Modest is Bodice" for some reason makes me laugh. Anyway...
That was the title of Rachel's activity at church today: Modest is Hottest.
I sighed just as heavily typing that as I did when I read it because I believe there is so much wrong with teaching our little girls (she's ten years old!) about modesty this way. I believe that modesty is important, sure, but I don't believe modest has anything to do with "hotness" and I certainly don't believe that I should be introducing "hotness" as a goal/standard/ideal when my daughter—who is still a child—is considering what to wear.
So we held a preemptive family night lesson to discuss what modesty means, largely drawing from this, this, and this (we didn't do the Doctor Who paper doll adventure but we did read the talk, look at the pictures, and discussed modesty in dress and behaviour at length). To quote from one of those links, "Phrases like 'Modest is Hottest' introduce ideas about sexuality that are not appropriate for eight year olds," or ten year olds.
