The award-winning actress was spotted soaking up the sun with husband Brian O'Driscoll in Dublin city centre yesterday.
And while she might have countless designers queuing up to dress her, she stepped out in a €55 quilted top from Topshop.
the 'Hexagon Quilted Jumper' is on sale here for €25, and while it's sold as a crop top for the daring - she opted to wear a top underneath to add a more conservative touch.

Her skinny jeans, oversized bag and retro sunglasses added to her low-key look.
Amy has become Ireland's most popular style icon, with pieces she is snapped in often selling out instantly, as Lennon Courtney designer Sonya Lennon dubbed 'the Amy effect' after their €125 silk top sold out when she wore it at The Stag premiere.
Designer Sonya Lennon said she was thrilled Amy had chosen to wear one of her items to a high-profile event.
"It's the Amy effect," Sonya added. "What she wears sells out and she's unaware of the power of her own persona."

The IFTA winner, who is still revelling in the success of her Irish comedy The Stag, turned heads last week at a State dinner in London with hubby BOD for President Michael D. Higgins' historic UK visit.
She stunned in a €295 sage-green lace dress with a cream satin slip which she bought from the Irish website Folkster.com, just days after winning in the style stakes at the IFTAs in Helen Cody.
And despite her incredible style selling power, Huberman is famous for always purchasing her clothing rather than simply borrowing a designer dress.
