A 37 inch bust measures the circumference around the fullest part of the chest, typically at the level of the nipples. This measurement falls within the 16-18 size range in standard US women's clothing, depending on brand and cut.
Bust size is determined by measuring around the torso at the fullest point, usually just below the armpits and above the breasts. A 37 inch bust is considered medium-large in most retail sizing systems. For reference, the average American woman's bust size is 38.5 inches, according to data from the Centers for Disease Control and Prevention (CDC) National Health and Nutrition Examination Survey (NHANES).
When shopping, a 37 inch bust may fit differently across brands. Some use a flat measurement, others include stretch. For example, a size 16 in a brand like Banana Republic may have a 37 inch bust, while the same size in Old Navy could run up to 39 inches due to looser construction. Always check the specific garment's size chart rather than relying solely on the labeled size.
Standard US women's clothing sizes are based on a combination of bust, waist, and hip measurements. A 37 inch bust typically corresponds to:
For example, a size 16 in a popular women's jeans brand like Levi's has a 37 inch bust. The same size in a sportswear brand like Lululemon may have a 38 inch bust due to performance fabric elasticity. Always compare the actual measurement to the garment's size chart.
Fit varies by style. A fitted blouse with a structured shoulder may feel tight at 37 inches if the shoulders are narrow. A relaxed sweater with stretch knit may accommodate the same bust with ease. Fabric composition matters: cotton blends stretch less than polyester-elastane blends.
Many assume that a 37 inch bust automatically means "large" or "plus-size." That's incorrect. Plus-size categories in US retail typically begin at 44 inch bust and above, according to the Fashion Institute of Technology (FIT) sizing guidelines. A 37 inch bust is within the mainstream size range.
Another common error is confusing bust with waist or hip measurements. The bust is measured at the chest's widest point, not at the natural waist. Measuring the waist at the belly button and the hips at the fullest part of the buttocks gives different numbers. Mixing these up leads to ill-fitting clothes.
Some brands label sizes inconsistently. A "size 16" in one catalog may have a 37 inch bust, while another may list it at 39 inches. This inconsistency causes confusion. The solution: measure your own body and match it to the product's size chart, not the label.
Comparing a 37 inch bust to larger sizes shows clear differences in fit and availability. The table below outlines typical size ranges and corresponding bust measurements:
| US Size | Bust (inches) | European Size | Typical Brand Range |
|---|---|---|---|
| 14 | 36 | 38 | ASOS, Zara |
| 16 | 37 | 40 | Banana Republic, Nordstrom |
| 18 | 38 | 42 | Old Navy, Macy's |
| 20 | 39 | 44 | Target, J.Crew |
The jump from size 16 to 18 adds just one inch in bust, but the visual difference is noticeable. A 37 inch bust fits snugly in a size 16, while a size 18 offers room for movement and layering. This small increment affects both comfort and appearance.
For those transitioning from a smaller size, a 37 inch bust may require adjusting expectations. A size 14 shirt with a 36 inch bust may feel tight at 37 inches, especially if the fabric lacks stretch. But a size 16 with 37 inch bust should fit comfortably if the design allows for ease.
I recently bought a navy sheath dress from a major retailer. The size chart listed a size 16 with a 37 inch bust. I measured my own bust at 37 inches and selected size 16. The dress fit snugly through the chest but allowed movement when raising my arms. The fabric had 5% elastane, which helped with stretch.
When I tried a size 14, the bust was too tight-buttons strained at the center. A size 18 felt loose, with excess fabric pooling under the arms. The size 16 was the correct fit. This confirms that matching your actual measurement to the size chart is essential, even when the size label seems close.
Understanding your 37 inch bust ensures better clothing choices. It's not a rare or unusual measurement-it's a common size in mainstream fashion. Knowing how it translates across brands prevents frustration and wasted money.
