Understanding Jackets Sizing
Tank tops are sleeveless garments that come in various styles and fits, from athletic racerbacks to casual muscle tanks. Sizing is primarily based on chest measurement and desired fit. Unlike t-shirts, tank tops show more of the arms and shoulders, so fit is critical for both comfort and appearance. Standard letter sizes range from XS to XXL, with chest measurements determining the appropriate size. Most tank tops are made with some stretch, allowing flexibility within each size category.
Tank top measurements focus on chest circumference and length from shoulder to hem. A size medium typically fits a chest of 38 to 40 inches and has a length of 28 to 29 inches. Armhole size varies significantly between styles, with racerbacks having narrow armholes for mobility and muscle tanks having large armholes for showing arms. The neckline also varies, from high crew necks to deep v-necks or scoops. Understanding these variations helps you choose the right tank top for your activity and style preference.
History of Jackets and Sizing Standards
Tank tops originated in the 1920s as athletic undershirts worn by swimmers and track athletes. The name comes from swimming tanks or pools where athletes competed wearing these sleeveless shirts. In the 1930s and 1940s, tank tops became popular as casual menswear, particularly the A-shirt or wife beater style with thin straps. Women's tank tops gained popularity in the 1970s with the fitness movement, featuring racerback designs for aerobics and dance.
Modern tank top sizing developed alongside athletic wear standards in the 1980s. Brands established size charts based on chest and length measurements, with fit categories like slim, regular, and relaxed. The muscle tank style emerged from bodybuilding culture, designed with oversized armholes to show off developed arms and shoulders. Today, tank tops serve both athletic and fashion purposes, with sizing adapted for different use cases from performance training to casual streetwear.
Common Jackets Styles Explained
Racerback tanks feature straps that come together between the shoulder blades, creating a T or Y shape on the back. This design allows maximum shoulder mobility and is popular for running, yoga, and CrossFit. Racerback tanks typically fit close to the body and are made from moisture wicking fabrics. Women's racerback tanks often include built in shelf bras for light support. The fitted nature means choosing the correct size is important to avoid restriction during movement.
Muscle tanks have large armholes that extend down the sides, sometimes reaching the bottom hem. This style is designed to show off arms, shoulders, and sometimes the sides of the torso. Muscle tanks are popular in gyms and bodybuilding communities. They typically fit looser than racerbacks and are sized more generously. The oversized armholes mean the garment drapes differently than standard tanks, so fit preferences vary widely among wearers.
Standard tanks or classic tanks have medium armholes and straight sides. They resemble t-shirts without sleeves and are the most versatile tank style. Standard tanks work for both athletic and casual wear. They come in various fits from slim to relaxed and can have crew necks, v-necks, or scoop necks. This style follows similar sizing to t-shirts, making it easier to predict fit based on your usual size.
How to Measure for Jackets
To measure your chest for tank tops, wrap a measuring tape around the fullest part of your chest, typically at nipple level. Keep the tape parallel to the ground and snug but not tight. For men, measure over bare skin or a thin undershirt. For women, measure while wearing a bra similar to what you will wear under the tank top. Record the measurement in inches and compare to brand size charts.
Length is measured from the high point of the shoulder, near the base of the neck, straight down to the bottom hem. This measurement determines whether the tank will hit at your natural waist, below it, or above it. If you prefer longer tanks that tuck into pants or cover your waistband, look for extended lengths or size up. For cropped styles that show midriff, check the specific length measurement as cropped can mean different things across brands.
Fit Considerations for Different Activities
Athletic tanks for running and training should fit close to the body to reduce bouncing and friction. Look for moisture wicking fabrics and consider racerback or fitted styles. The armholes should allow full arm movement without the garment riding up. For high intensity workouts, choose a size that stays in place during jumping and reaching movements. Many athletes prefer to size down in athletic tanks for a snugger fit.
Gym tanks for weightlifting can be looser, especially muscle tank styles. These tanks prioritize comfort and showing physique over performance fit. The large armholes allow unrestricted arm movement during exercises like overhead press and lateral raises. Some lifters prefer very oversized muscle tanks that drape loosely, while others want a more fitted look. Personal preference plays a big role in sizing for gym tanks.
Casual tanks for everyday wear come in various fits from slim to relaxed. Consider how you plan to wear the tank when choosing a size. Slim fit tanks worn alone should fit close without being too tight, while tanks worn as layers can be sized more loosely. Women's casual tanks often feature fashion details like lace, buttons, or prints that may affect fit. Always check measurements rather than relying solely on size labels.
Men's vs Women's Jackets Sizing
Men's tank tops are typically cut straighter through the body with less tapering at the waist. They have wider shoulders and larger armholes overall. Men's sizing is based on chest measurement, and fit categories include athletic, regular, and loose. Standard men's tank tops have crew or v-necks and come in neutral colors, though fashion tanks feature more variety.
Women's tank tops are cut with more shaping through the waist and bust. They have narrower shoulders and smaller armholes designed to accommodate the female form. Women's sizing may use numeric sizes (0, 2, 4, etc.) or letter sizes (XS, S, M, etc.), and measurements should include bust, waist, and hip. Many women's tanks are designed to be worn with bras, while others have built in shelf bras or padding. The variety in styles means fit can vary significantly between brands.
Fabric and Stretch Considerations
Cotton tank tops have minimal stretch and require accurate sizing. They are comfortable and breathable but may shrink in the wash if not pre-shrunk. 100 percent cotton tanks should fit comfortably when new because they will not stretch to accommodate movement. If a cotton tank feels slightly snug, it will likely be too tight after washing. Consider sizing up if between sizes.
Blended fabrics with cotton and polyester or spandex offer more stretch and recovery. These tanks are more forgiving in fit and work well for athletic use. Look for at least 5 to 10 percent spandex or elastane for good stretch. Performance fabrics like moisture wicking polyester blends are designed for workouts and typically fit true to size with some give. These fabrics maintain their shape better than pure cotton.
Practical Tips for Choosing Jackets Sizes
When shopping online, always consult the brand specific size chart. Tank top sizing varies more than other garment types because of the variety of styles and armhole sizes. Read customer reviews to learn if items run small, large, or true to size. Many reviewers mention their usual size and what they ordered, plus how the fit worked out. This information is invaluable for online purchases.
If you are between sizes, consider the tank top style and your intended use. For athletic tanks with fitted designs, size down for a snugger fit. For casual or muscle tanks with loose cuts, size up for more comfort. When in doubt, remember that too loose is generally more comfortable than too tight, especially in garments that show a lot of skin. Finally, check the return policy before buying, as trying on is often the only way to know if a tank top fits correctly.
