Rachel McAdams Debuts Uber Sheer Valentino Dress at TIFF...

It seems every celebrity has a secretly sublime sibling (apologies) of late, not that we're complaining. 

For those of you here for the sheer dress; behold Rachel Mc Adams, looking resplendent in a transparent floral Valentino number at the Spotlight premiere at the Toronto International Film Festival...

For those of you here to have a hawk at her brother; Daniel Mc Adams was her date at the 'after' party at Soho House on Monday.

Before you ask, yes he's married.

Are you a fan of the sheer look, or do you find it distracting - you'd rather see the dress than the underwear, Godnammit!
