First, read the English article below.

Choose the bra you feel most comfortable in--it should be snug but not dig into your sides. Your nipples should be about halfway between your elbow and shoulder. If they are lower, tighten the straps to lift. You can also measure without a bra, but it may be slightly more challenging when things can move around. Standing in front of a mirror, use a soft tape measurer to measure around your ribs right under your breasts. This is also where the band of your bra wraps around your torso. Pull the tape tight. Write down this measurement.  Use the mirror to make sure the tape is exactly parallel to the floor. If the measuring tape is not in a straight line around your body and at an angle, you will not get an accurate measurement.  Don't pull the tape so tight it's like you are wearing a corset. Just make sure it is squeezing your body snugly.  If your measurement is a fraction (like 33 1/2 inches), round up to the nearest whole number (34 inches).  Band sizes are measured in even numbers, so if your measurement was odd, you may want to try one size up and one size down (if you measure 35 inches, try both the 34 and the 36 size bra), but round up for now. Wrap the measuring tape around your back and measure your breasts at their fullest point, usually at the nipple. Write down this measurement.  Because your cup size can fluctuate based on hormones and bloating, try to measure on a day when your breasts feel relatively normal.  If you are concerned about your posture (maybe you slouch), try bending forward at the hips to a 90 degree angle, or until your body forms an L shape. Then measure your bust from that position.  Don't pull the tape tight like you did with your band measurement. As with the band measurement, round up to the nearest whole number if your measurement is a fraction.  Again, be certain the tape is straight across your back. The measuring tape should not angle up from your back toward your nipples. All women have one breast that is larger than the other, so be sure you are measuring to the fuller... 

Now, please write a short abstract for it in Indonesian. Abstract:
Kenakan beha yang nyaman, pas pada badan, dan tanpa lapisan tambahan. Cari ukuran band. Cari ukuran dada. Kurangi ukuran band dengan ukuran dada. Kombinasikan ukuran cup dengan band, dan Anda pun menemukan ukuran beha Anda. Ingatlah bahwa ukuran cup "tidak" sama untuk ukuran band berbeda. Minta bantuan dari ahlinya jika Anda membutuhkan.
