If you always thought there were only two kinds of boobs—big or small—your mind is about to be blown. According to bra company ThirdLove, women have one of seven different sets of headlights.

“During our product design process, we discovered that getting a great fit was about identifying the style that best suits your natural shape,” says Ra’el Cohen, vice president of design and product development at ThirdLove.

While ALL types of lady lumps are perfectly normal and beautifully imperfect, knowing your shape can help you get the best bra fit. Skim the brand’s Breast Shape Dictionary to I.D. your pair—and shop accordingly.

Asymmetric: One breast is larger than the other; ranges from minor (barely noticeable) to more pronounced (as pictured).

Look best in: Bras with removable pads, so you can wear a pad (or two) on the smaller side to even out your look.

Bell Shape: Generally heavier breasts; narrower at the top, then drastically fuller toward the bottom.

Look best in: Full-coverage styles. Because the breasts are heavier, they can drag down the shoulders, causing the straps to slip (and reduce support).

East West: A gentle slope from top to bottom, but out to the sides; nipples point in opposite directions.

Look best in: Push-up or T-shirt styles, which flatter your natural shape while comfortably bringing your breasts closer together.

Side Set: A wide space in between the two breasts; nipples point a little more forward than East West.

Look best in: Balconette styles, which have more fabric above the cups to disguise a larger gap between breasts.

Slender: A little wider at the top, narrower at the bottom; generally skinny without a lot of breast tissue.

Look best in: Plunge styles, with or without push-up material. The plunge helps pull the breasts toward the middle to create a bit of cleavage.

Tear Drop: Similar to Bell Shape but with a much gentler slope; easily identifiable from the side.

Look best in: Plunge styles, with or without push-up material. The deeper neckline and cups create lift, which helps fill in the shallower top of the breasts.

Round: Equally full on top and bottom; often surgically enhanced, but not always.

Look best in: Balconette styles, which show off your perky shape. Consider Round breasts to bras as the Oval face to haircuts: They can pull off anything. (Lucky you.)

So, if you’re comfortable sharing, let us know which style you are and what type of bras not only flatter your shape but provide you with the necessary support.
