The Brazilian supermodel dressed up as a sexy version of Red Riding Hood, completed with a tiny low-cut corset inspired costume with a frilled and ruffled skirt and a red hood.

The Victoria's Secret Angel tuned heads in her racy ensemble, and added on a pair of comfortable black flats.

Her little boy was dressed up as a Dalmatian dog in a black and white spotted jumpsuit, floppy ears, red waist coat and a fire dog's hat.
