She looks all white: Britney Spears is making the most of her downtime on a family break in Hawaii

Going for a relaxed holiday vibe, the singer bypassed a bra when slipping into a flowing white maxi dress.

The sleeveless, halter-neck garment showed off Britney’s toned arms and brought out the Stronger hitmaker’s golden tan.

The dress cinched and ruffled at the waist, giving it enticing texture and shape, and fell past Britney’s knees, protecting her modesty while still allowing her to flash her taut calves.

The 5ft 4in beauty teamed the dress with chunky peep-toe platforms, which helped her stand tall as she indulged in a large ice cream cone.
