Look hot this Halloween with these body-flattering costumes that will garner treats rather than tricks.

Best Costume to Downplay a Bigger Bottom Half: Sexy Witch

Best Costume to Downplay a Bigger Bottom Half: Sexy Witch
An oversize witch hat does the trick to draw all eyes upwards—towards your pretty face and away from a bigger bum. Wear with a super-slimming LBD and blackout opaque tights to lengthen and lean the look of a Triangle figure. Hanes hosiery has a great selection to suck you in at all the right places and make you look fabulous. Feeling extra festive? They have a shimmery version, too—perfect for the holiday season.

Pier 1 Imports animal print witch hat, $19.95

Best Costume to Create Curves: Grecian Goddess

Best Costume to Create Curves: Grecian Goddess
Necklines like halters or one-shoulder styles give the illusion of dimension and a curvier silhouette for Ruler shapes. Anything with a high neck or cutaway sleeves will also show off slender arms. Add lots of gold accessories, strappy heels and pretty makeup to complete the gorgeous goddess look.

JS Boutique sleeveless one-shoulder dress, $129

Best Costume to Showcase an Hourglass Figure: Belly Dancer

Best Costume to Showcase an Hourglass Figure: Belly Dancer
Show off your enviable Hourglass shape and toned tummy in a sparkly crop top. Pair it with silky drawstring pants. A styling tip I heard from Kelly Osbourne: If you’re still nervous about showing off your less-than-perfect abs, wear a thin layering tank (like this scoop neck tank from Maidenform) underneath it for extra coverage. Go all out with your makeup and accessories—think stacks of bangles and body shimmer.

Topshop embellished fringe camisole, $80

Best Costume to Show Off Great Legs: Army Girl

Best Costume to Show Off Great Legs: Army Girl
Downplay an Inverted Triangle’s bigger upper half and showcase your sensational legs in on-trend short faux-leather shorts, a cute baseball cap, a camo tee and sky-high heels. You’ll also be on-trend since military is one of the biggest trends this fall.

Best Costume to Tone a Tummy: Pretty Devil

Best Costume to Tone a Tummy: Pretty Devil
Knock them dead at your Halloween party in a red ruched dress and appropriately festive accessories, like patent pumps and a devil-horned headband. Anything that is ingeniously draped across your torso, like ruching or gathering, will magically melt away a Circle’s fuller mid-section and give the illusion of a slim waistline.
