Well, here is what the Old Testament says:
"Thou shalt not wear a garment of divers sorts, as of woollen and linen together. Deuteronomy 22:11
I will punish ... all such as are clothed with strange apparel. Zephaniah 1:8
I don't know whether Sarah's clothes were made of blended fabrics or if God considers them strange. Someone should check into that.
But the big problem comes from the New Testament. Here's what it has to say:
Women adorn themselves in modest apparel, with shamefacedness and sobriety; not with braided hair, or gold, or pearls, or costly array. 1 Timothy 2:9
Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel. 1 Peter 3:3
So costly apparel is out -- for women, anyway. I think even God might consider $150,000 costly.
And lastly we should ask, what would Jesus wear?
And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. ... Therefore take no thought, saying, ... Wherewithal shall we be clothed? Matthew 6:28-32
So if Sarah cares about what Jesus said, she should either wear anything -- or nothing at all. Just like the lilies.
