Celebrity Bikinis: Best and Worst

We give Aubrey O’Day an A for effort, but her low set push up top puts the “girls” in an awkward position. For a flattering padded piece, try purchasing a bikini top that is sized like a bra to ensure your best fit.

Ciara shows off the perfect amount of skin in her black knit sarong. The structured fit and high-waisted tie balance her frame, while showcasing her killer abs. Can you say crunches?

Katherine Heigl looks summer-ready in her black bikini and over sized sunglasses. However, the sarong side knot, loosely slung around her hips, creates an illusion of a larger frame, defeating its purpose.

The Orange County Alum confirms she can still rock it on the beach in this summer number. Rachel Bilson proves that the LBB (Little Black Bikini) is a wardrobe staple no girl should be without.

Don’t get us wrong, Elisabetta Canalis has a body to make any girl green with envy but her triangle top leaves little to the imagination. The unpleasant ‘under boob’ is a bikini no-no that leaves us wanting to tuck the girls back in.

Bethenny Frankel skips the frilly details in this neon bikini. By choosing a simple style and a monochromatic color, this SkinnyGirl mama gets our pick for best neon bikini.

Karina Smirth parties in Vegas poolside in a bright blue and yellow bikini. With so much neon and a style that screams 1985, this suit overwhelms the Dancing with the Stars svelte frame, leaving her sans perfect score.

The soon to be Mrs. Lachey looks red hot (or should we say ‘pink hot’) while vacationing in Mexico. This suit accentuates Vanessa Minnillo’s curves in all the right places giving her that va-va voom look. We must say, those wedding workouts are really paying off.

Olivia Palermo is never one to disappoint when it comes to her fabulous sense of fashion, but this bikini gets an F for un-flattering. This stringy suit gives leaves her pint sized figure lacking any shape. For petite girls, try a bandeau top for a curvier look.

Maria Menounos is the definition of beach babe in this black number. The Greek-American bombshell goes for the embellished look by keeping her suit color subdued and pairing her side tie bottoms with a criss-cross top.

Michelle Rodriguez’s white top with ruffles, patterned sarong, and jeweled clasp overpower her natural beauty while hitting the beach in Spain. An easier way to give your suit some added ‘oomph’ is to pair it with a chunky necklace or floppy hat for a simple yet embellished look.

Kelly Rowland hits a high note in this lime twisted bandeau giving her chest a great shape. This fitted top gives her just enough cleavage without spilling out.

Its surf’s up for this Hilton Heiress. We adore this print, but the straight across bandeau top does little for Nicky Hilton’s shape. To enhance your bust, pick a bikini top with a sweetheart cut for a feminine silhouette.

Diane Kruger gives her slim figure some added oomph while mixing it up in this panther inspired suit. This one piece gives her boyish frame a little boost with its high cut and thick straps.

The Barbados beauty shows off her killer curves in this black one piece, however its high cut creates the illusion of larger legs with its tight fit.

Audrina Patridge knows how to wear bikinis, and wears them well (I think we’ve see her in more bathing suits than clothing). We adore this uniform tribal patterned suit that that gives her tanned skin an added pop.

We love the shape of Ashley Tisdale’s suit, but can’t say the same for her mix matched motif. This multi patterned print is one we doubt Sharpay (no we haven’t gotten over High School Musical yet) would be proud of.
