The topic of modesty provokes a lot of impassioned discussion, both online and offline. This Bible verse is perhaps the most commonly cited one:
In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array. (1 Timothy 2:9 KJV)
How come I rarely hear anything said about the “costly array” bit? I’m sure someone somewhere has, but I’ve more often heard this text mentioned in terms of covering up the flesh, and occasionally some Christians eschewing jewellery and back in the day some would forego braiding hair. But obviously expensive clothing, not so much.
