The biggest shock of the 2012 SAG Awards didn’t come in an envelope tonight.

No, the biggest surprise was that Tilda Swinton didn’t wear Haider Ackermann.

The British actress chose a rather different look, wearing a custom Lanvin dress.

Known for her unique personal style, Tilda was quite on-trend with the rest of the carpet in the flowing off-white gown.

Long sleeves and her signature blonde crop maintained some of the classic Tilda look.

Even though Tilda does minimalist often, we can’t help but feel like this look falls flat, even though she opted for a berry lip colour, Pomellato statement rings and a gold Fred Leighton cuff.
