Judging by material: the core determining comfort

1. Fabric Composition

• Natural fibers:

• Cotton: It has good breathability and strong moisture absorption, suitable for daily wear, especially for sensitive skin. High quality cotton material has a soft touch, natural color, and is not prone to pilling.

• Modal/Lanjing Modal: Made from wood pulp, it is softer and smoother than cotton, with good drape and 1.5 times the moisture absorption capacity of cotton. It is suitable for people who pursue ultimate comfort, but its wear resistance is slightly inferior.

• Real silk: luxurious texture, excellent breathability, skin friendly, but expensive and difficult to maintain (requiring hand washing and avoiding exposure to sunlight).

• Synthetic fibers:

• Polyester fiber (polyester): commonly found in quick drying underwear, with high strength and resistance to deformation, but poor breathability, and may be stuffy and hot if worn for a long time.

• Nylon (nylon): It has good elasticity and wear resistance, and is often blended with spandex for shaping underwear (such as adjustable bras), but its breathability is average.

• Spandex (Lycra): It has excellent elasticity, usually accounting for 5% -20%, and is used to increase the fit and resilience of underwear. If the content is too low, it is easy to loosen, and if it is too high, it may become tight.

• Special Material:

• Bamboo fiber/bamboo charcoal fiber: It is claimed to have antibacterial and deodorizing functions, but the actual effect depends on the testing report, and some products may contain chemical additives.

• Graphene fiber: a popular "antibacterial" material in recent years, attention should be paid to whether there is authoritative certification to avoid false advertising.

2. Fabric Texture

• High quality fabric has a delicate and soft touch, without any roughness or itching sensation; Poor quality fabrics may feel stiff and make a rustling sound when rubbed against the skin.

• Observing the fabric in front of the light, the quality is better with uniform texture and no obvious defects (such as jumpers and burrs).

Check the process: affects durability and comfort

1. Suture Technique

• Car stitching: The stitching of high-quality underwear is neat, fine, and even (about 4-5 stitches per centimeter), without any jumping or leaking threads; The seams are smooth and will not rub against the skin (such as the crotch of underwear or the sides of bras).

• Non marking technology: Some underwear is bonded by hot pressing (without needle and thread stitching), suitable for pairing with tight clothing. The edges need to be checked for smoothness and the risk of delamination.

2. Cutting And Splicing

• The cup cut of the bra should fit the chest shape (such as full cup and half cup designs are reasonable), with no wrinkles on the cup surface and symmetrical left and right; The crotch cut of underwear should be loose and moderate to avoid pinching or trapping the hips.

• The joint (such as the connection between the bra bottom and the cup) should transition naturally without any protrusions or hard edges.

3. Auxiliary Material Quality

• Shoulder straps/elastic bands: High quality shoulder straps have good elasticity and strong resilience, and are not easily deformed after repeated stretching; Poor quality shoulder straps may become loose, slip, or pinch the shoulders.

• Buckle/Hook: The bra back buckle should be firm, smoothly inserted and removed, and the metal part should be free of burrs to avoid scratching the skin; The elastic band at the waist of underwear should be soft and elastic, without curling edges.

• Decorative components such as lace and rhinestones should be sewn firmly without any risk of falling off, and the edges of the lace should be smooth and not prick the skin.

View design: ergonomic fit

1. Bra Design

• Cup support: The cup cushions (such as cotton pads and memory foam) of high-quality bras have uniform thickness and no risk of displacement; The steel ring (if any) should be rounded, fit snugly against the lower edge of the chest, not uncomfortable, and wrapped in soft fabric.

• Side wing width: The width of the side ratio (under the armpit of the bra) is moderate, which can effectively retract the accessory breasts without compressing the armpit lymph nodes (generally recommended to be 2-3 centimeters or more).

• Chicken heart height: The height of the chicken heart (the part connecting the left and right cups in the middle of the bra) should be selected according to the chest shape. A low heart is suitable for small breasts, while a high heart is suitable for large breasts (to increase stability), but should not compress the sternum.

2. Underwear Design

• Crotch fabric: The crotch of underwear must be made of natural fibers (such as pure cotton) and have at least a double-layer design to ensure breathability and antibacterial properties; Poor quality underwear may use synthetic crotch, which can easily cause discomfort in the intimate area.

• Waist design: The waist of high waisted underwear should fit the curve of the waist without curling edges; Low waisted underwear should pay attention to the length of the crotch area to avoid revealing or pinching the buttocks.

• Cutting curve: The hip circumference of underwear should have a natural curve to avoid the "triangle area" being too tight or too loose. High quality underwear should have no obvious creases after wearing.

Check details: reflect the brand's level of dedication

1. Labels And Identification

• Regular brand underwear should have clear washing labels, indicating fabric composition, size, implementation standards (such as GB 18401-2010 "National Basic Safety Technical Specification for Textile Products", and must comply with Class B or Class A standards. Products that come into direct contact with the skin must be Class B or above), manufacturer information, etc.

• Avoid purchasing products without labels or with unclear label information, as they may be low-quality three no products.

2. Odor And Staining

• After opening the new underwear, there should be no pungent odor (such as formaldehyde odor or industrial dye odor). If the odor is strong, it may exceed the formaldehyde limit and caution should be taken.

• Dark colored underwear can be lightly rubbed on the fabric and observed for color fading (especially black and red). Products with severe color fading may have unqualified dyes and long-term wear is harmful to health.

3. Try On Experience

• Bra: The shoulder straps do not slip off when worn, and the cups completely wrap around the chest without any empty cups or pressure on the chest; When lifting the hand, the steel ring does not move up and there are no creases on the back.

• Underwear: No crotch or rolled edges when walking, and the elastic band at the waist is not tight; After prolonged sitting, there is no dampness in the crotch area, and the fabric fits snugly but does not compress the skin.

Other reference factors

• Brand and Price: Although price does not necessarily equal quality, well-known brands such as Huage Er, Aime, Uniqlo, etc. usually have stricter quality control and more guaranteed after-sales service; Underwear that is too cheap (such as below 10 yuan per piece) may cut corners in material and craftsmanship.

• Changes after washing: After multiple washes, high-quality underwear is not easily deformed or faded, and the elastic band maintains good elasticity; Poor quality underwear may experience issues such as pilling, shrinkage, and looseness after a few washes.

• Functional adaptability: Choose functional underwear according to needs (such as high support sports underwear and loose and breathable maternity underwear), to avoid blindly pursuing "internet famous styles" and ignoring actual needs.
