....Let's save the "shock, horror, OMG" until we get something worthy of it. Underwear actually showing or supposed lack thereof would probably do it although I think IMO a bra strap is merely a very minor wardrobe malfunction. Actually, I think KittyAtlanta has the right of it, the 80's were a sort of fashion watershed.
IMHO she is an "official public figure" now - and especially as the Engagement is only a few weeks away, it was clear, that the photographers would use the opportunity to make 1000 pics.
She must have been Aware about this.... this Outfit was neither a "shock", nor "Horror", but a nice White summerly Dress would have made the difference..... and about 100 less nasty Posts in this thread
So she should have been more clever with the choice of her clothes. She KNEW, she was in the Center of Attention - so why didn´t she Dress likewise. Like she did in the last years.

I'll say this, at least she is wearing a bra.
But it's not a 'wardrobe malfunction'. It's what happens to us all and no one thinks a second thought. In fact, she is wearing an undergarment. She is not showing her black bra underneath. 
I think it''s because she is so pale. I thought the same thing - something seemed 'off ' when I then realized that we are accustomed to seeing a bronzed body in a bikini. A less vivid color - something more in sync with the actual color of her body would have blended more. It's like choosing a dress color to accentuate one's natural face coloring. The bikini itself is fine, of course. It's the vivid color against the pale skin color that jumps out as unusual. JMO.
