Regardless of spring, summer or autumn and winter, underwear and aunties are often ranked as the top problems for girls.
After all, even after wearing underwear for many years, there are still many worries and embarrassments in daily life, such as underwear shoulder straps often slipping, streaks of red marks on the back, empty cups, stuffy heat and airtightness, and tight underwear fabrics. People are also easily deformed ...
Today, from a scientific perspective, I will inventory and answer some common underwear problems for sisters (boys can also check for their girlfriends if they accidentally click in).
Why do underwear straps always slide down?
Because of "sliding old shoulders"? ? ?
● The skin is "too slippery"
The human chest is a whole, and the subcutaneous fat and skin always slide along with the movement of the bones. The sliding of the skin gradually increases toward the base of the arm where fat is deposited and filled with more fat, reaching the maximum at the bottom of the back and front armpits.
With the movement of the upper limbs, the back skin slides diagonally upward along the central waist, posterior armpit, and outer upper arm; the chest skin slides straight upward along the subcostal waist, front axilla, and outer upper arm. So the shoulder straps will also slide as the skin slides.
● Shoulder straps are too long and too loose
The bra cup is too large and the shoulder straps are too long and loose, resulting in the shoulder straps not being firmly fixed on the shoulders and easily slipping off.
You can appropriately adjust the lower and lower buckles on the shoulder straps to keep them at the appropriate tightness, or choose shoulder straps with moderate elasticity.
Let me tell you a little secret that many people don't know: choose the anti-slip 8-character buckle in the middle below for the shoulder strap buckle, which can easily adjust the length of the shoulder strap. The shoulder strap is more stable and less likely to slip off.
● The shoulder strap position is incorrect.
The shoulder strap position is not fixed in the depression of the human body's shoulder, which is also one of the reasons for the shoulder straps to slip. The best position of the shoulder strap is between the shoulder blade and the clavicle. Adjusting the position of the shoulder strap can alleviate the slippage of the shoulder strap to a certain extent.
For example, when people with thick/wide shoulders wear underwear, the shoulder strap position should be centered or a little farther inward toward the neck. For thin/narrow shoulders, the position of the shoulder straps should be centered or a little farther toward the shoulders .
● Slipping shoulders + inappropriate shoulder strap style
Most Chinese women have rounded shoulders and slide slightly to the outside, that is, slipping shoulders, which can easily cause the shoulder straps to slide down. You can choose a suitable shoulder strap according to your shoulder shape, or change the strap material.
For example, avoid choosing shoulder straps whose fabrics are too slippery, and choose shoulder strap fabrics with relatively high friction, such as yarn, ribbed tissue or silicone non-slip material , etc. Choosing two shoulder straps on one side instead of one shoulder strap on one side can also increase a certain amount of friction.
You can also replace the common two parallel shoulder straps with cross-back type, hanging neck type (hanging type, diagonal type) , T-shaped and back-gathering . Thick/wide shoulders can choose wider shoulder straps, thin/narrow shoulders can choose narrower straps.
How to choose underwear correctly?
Underwear made of chemical fiber, with poor quality, rough and non-breathable fabrics, and too tight, too small or too large, can easily cause skin allergies, irritation, prickly heat, strangulation, squeezing of the breasts, empty cup slippage, etc. question.
If you want to avoid or solve these problems, you can choose comfortable cotton, silk, modal and other fabrics or blended fabrics that meet the requirements of soft feel, good breathability, washability, and colorfastness.

In addition, you also need to choose the right underwear according to your breast shape.
Step 1: Measure the size of the upper and lower bust
The upper bust refers to the data obtained by circling around the nipple, and the lower bust refers to the data obtained by circling around the area below the breast. The difference between the upper bust minus the lower bust In which cup range, you should wear bra of which cup (A/B/C/D) , and the bottom size is Choose according to the lower bust value , such as 75B ,80D.
Step 2: Determine the breast shape
Breast shapes can be mainly divided into disc type/hemispheric type/conical type/spindle type.
Disk breasts are shaped like a plate, with a large base but not a high bulge.
Hemispherical breasts are shaped like a bowl, round and full, with a higher bulge.
The cone breast is shaped like a cone, with a small base and high bulge, making it easy to empty the cup.
Spindle breasts are shaped like spindles and papayas, with longer breasts.

Step 3: Choose the cup style according to the breast shape
Disc-shaped breasts are suitable for wearing shallow cup Three-quarter cup or one-half cup underwear (French triangular cups are also suitable, It is not easy for the empty cup to shift).
Hemispherical breasts are suitable for three-quarter cup or full cup with a rounded and large wrapping area.
Cone-shaped breasts are suitable for wearing a moderate cup depth of 1/2 cup or 3/4 cup.
Spindle-shaped breasts are suitable for three-quarter cup or full cup.
Step 4: Choose the underwear type
According to different scenarios and needs, choose daily underwear, sports bras, tube tops, bra stickers, bikinis and other different underwear types. It is recommended to try on regular professional underwear brand stores before purchasing.
How to clean and care for underwear? How often should it be replaced?
Underwear containing steel rings, lace and other fragile materials should be washed by hand as much as possible. If you are too lazy to wash the underwear by hand, you can put it in a special laundry bag and machine wash it to avoid damaging the underwear and deforming it.
When drying, you can hang the underwear upside down or fold it in half and hang it on a hanger, with the shoulder straps hanging downward to avoid sun exposure.

Underwear is the same as underwear. There is no absolute time requirement for the frequency of replacement. It does not mean that you must abandon your old love for a new one in a few months.
But if the underwear has problems such as exposed steel rings, deformed cups, or inappropriate size, , or simply because you are tired of wearing them and want to change them, then you have to change them.
Will your breasts sag if you don’t wear underwear?
Don’t worry, under normal circumstances, the breasts will not sag because of not wearing underwear. The real culprits of sagging breasts are gravity, age, etc.
The function of underwear is actually to fix shock absorption, make clothes more upright and look better, and solve the problem of bulges. It is not to prevent sagging. Whether to wear underwear or not mainly depends on you.
However, when exercising, it is more recommended to wear professional sports bras to protect the breasts (especially big-breasted girls) to prevent the breasts from shaking violently, causing pain and sports injuries.
During the lactation period, the breast size becomes larger. You can also wear special nursing bras to improve comfort and support, and to facilitate breastfeeding.
Finally, people always ask how to make breasts bigger? It is really a drought that kills people, and a flood that causes waterlogging.
The papaya and pig trotters you often eat, the soy milk and coconut milk you drink, and the massage and kneading exercises you do cannot make your breasts really bigger. (visually) The only ways to make your breasts bigger are Getting fat, doing breast training, and enlarging your breasts .

Besides, small breasts are also good. In winter, you can wear more clothes without wearing underwear. When exercising, you don’t have to worry so much about your breasts dangling around or walking on a clothes rack~
In fact, no matter what Big breasts or small breasts, are all part of our body. Big breasts do not mean big breasts and brainless, and small breasts do not mean airports. There is no need to be ashamed or ridiculed. The only thing that is linked to them is this word - beauty .
