Decoding Size 38: Your Guide to Understanding U.S. Clothing Sizes

For anyone navigating the global landscape of fashion, whether shopping online from an international retailer or simply trying to understand a tag on a imported garment, the question “What is size 38 in U.S. clothing?” is a common and crucial one. The number 38 stands as a significant benchmark in sizing, but its U.S. equivalent is not a single, straightforward answer. It acts as a key, unlocking different doors depending on which part of your wardrobe you’re looking to build. Understanding this conversion is the first step to a confident and successful shopping experience, ensuring that the clothes you order are the clothes you’ll love to wear.

The primary reason for this complexity lies in the different sizing systems used around the world. The number 38 is predominantly featured in European sizing, a system based on precise body measurements in centimeters. A European size 38 typically corresponds to a bust measurement of approximately 94-96 cm and a hip measurement of around 98-100 cm. The United States, however, uses its own unique numerical and alpha system, which is more arbitrary and can vary significantly between brands. This is why a U.S. size 8 from one designer might fit differently than a U.S. size 8 from another, adding another layer to the puzzle.

To truly answer the question, we must break it down by garment type.

Women’s Clothing: Dresses, Tops, and Blouses

In the realm of women’s fashion, a European size 38 most commonly translates to a U.S. size 8 or a Medium (M). This is the standard conversion you will find on most international size charts. A U.S. size 8 generally fits a bust of 36.5 inches, a waist of 28.5 inches, and hips of 38.5 inches. The “Medium” (M) designation in the U.S. often aligns with these same measurements, making it a reliable ready-to-wear size for a wide range of clothing, from tailored blouses to casual knit tops and day dresses.

However, this is where the crucial caveat of “vanity sizing” comes into play. Many contemporary American brands have gradually adjusted their size charts over time, making numerical sizes larger than their standard measurements imply. In a store that practices significant vanity sizing, a woman who typically wears a U.S. 8 might find herself comfortably fitting into a U.S. 6 or even a 4. Consequently, a European 38 could sometimes feel like a U.S. 6 in these specific brands. This is why, when in doubt, consulting the specific brand’s size chart and relying on your actual body measurements in inches or centimeters is always the safest strategy.

Women’s Bottoms: Pants, Jeans, and Skirts

The conversion for bottoms follows a similar but distinct path. A European size 38 in pants or jeans typically corresponds to a U.S. size 8. U.S. women’s bottom sizes are usually based on waist and hip measurements. A size 8 generally indicates a waist of around 28-29 inches and hips of 38-39 inches. It is also frequently labeled as a Medium. The key difference with jeans is the inclusion of inseam and fit (e.g., skinny, bootcut, high-waisted), but the waist size starting point remains consistent.

Men’s Suiting and Jackets

The meaning of “size 38″ shifts dramatically when we enter the men’s department. For men’s suits, sport coats, and blazers, a size 38 is a direct U.S. measurement. It refers to the circumference of the chest in inches. Therefore, a man’s suit jacket labeled size 38 is designed to fit a chest measurement of 38 inches. From this chest measurement, other dimensions are proportionally derived. A U.S. size 38 Regular suit jacket typically fits a man with a 38-inch chest and is designed for someone around 5’10” to 6′ tall. It’s important to note that this is different from the European suit sizing, which would be 48 (as European suit sizes are typically the chest measurement in centimeters divided by 2).

The Importance of Accurate Measurement

Given these variations, the single most powerful tool for navigating size conversions is a soft measuring tape and the knowledge of how to use it. For both men and women, knowing your key measurements—bust/chest, waist, and hips—is indispensable. Compare these numbers directly to a brand’s detailed size chart rather than relying solely on the standard conversion. Pay attention to the garment’s “fit notes” as well; an “oversized” U.S. Medium will require a different approach than a “fitted” U.S. Medium.

Ultimately, understanding that a European size 38 is a versatile U.S. 8 or Medium for women and a specific chest measurement for men demystifies a significant portion of international shopping. It empowers you to move beyond the guesswork and build a wardrobe that fits beautifully, no matter where the clothes were made or which sizing system they use.
