A black, down-to-there backless Kaufmanfranco dress is how a pregnant Blake Lively chose to adorn her bump during Tuesday night's L'Oreal Women of Worth Event in New York.
But just as attention grabbing as the dress, was the actress and Preserve.com founder's hair color - or, rather, lack thereof - which had her roots appearing just about as dark as the slinky number she wore down the red carpet.
Pregnant with her first child (her husband is the equally toasty golden haired, Ryan Reynolds) Lively is most likely forgoing the typical and potentially toxic maintenance that comes with having long blonde locks.
And of course on her, it just sort of works. There's no harsh line telling the world that she stopped monthly salon visits exactly six weeks ago, no stark color blocking effect that would make most people scramble for their nearest hoodie.
'Blake has decided to not color her hair at all, thus growing out her darker roots,' says L'Oreal celebrity hair colorist, Kari Hill, who doesn't work with the actress but observes that Lively's hair color seems to be a double process base with highlights. Since creating highlights doesn't require the dye to touch the scalp (the main controversy with hair color during pregnancy), Hill recommends just doing the highlights to help blend the growth line and create a subtle ombré effect.
Softening the look of darker roots is another option Hill recommends to pregnant women seeking an alternative. 'This is actually something that we do in the salon multiple times a day,' she says. 'To soften the roots, I would use a gloss that is a couple shades lighter than the root color to help all the shades blend.'
For an at-home option, Hill suggests the L'Oreal Paris Ombré Touch Hair Coloring Kit ($10.99) which has an applicator that allows users to pick and choose where they want color to go. 'This will help to break up the hard line of growth,' says Hill. 'And lightens up some areas for a 'sombré' effect.'
'Sombre' for anyone who doesn't speak hair, is a term people are using to describe a 'subtle ombre' style of grown out highlights that stem from a mainly dark base.
Leave it to Lively to help ignite a trend by doing nothing more than being mindful of her future spwan.
