St. John Knits has established itself as a premier American fashion house, renowned for its luxurious knitwear and sophisticated designs. Understanding the brand’s sizing philosophy is paramount to ensuring a flattering and comfortable fit, reflecting the quality and elegance inherent in each garment. This introduction serves as a foundational guide to navigating the St. John sizing system, catering to a global clientele with diverse body types.
Unlike some designers who adhere strictly to vanity sizing, St. John generally maintains consistent and accurate measurements. However, subtle variations can occur, particularly with knit fabrics that possess inherent stretch and drape. Therefore, consulting the detailed size charts provided – encompassing US standard, numeric, and international conversions – is highly recommended.
This guide will delve into specific measurements for bust, waist, and hips, correlating them to corresponding St. John sizes. We’ll also address unique considerations for specific garment types, such as knit dresses, jackets, and coats, offering tailored recommendations for achieving the perfect silhouette. Ultimately, the goal is to empower you with the knowledge to confidently select St. John apparel that celebrates your individual style and body shape.
Understanding St. John’s Size Philosophy

St. John’s sizing approach centers on delivering a consistent and flattering fit that complements the luxurious quality of its garments. The brand prioritizes accurate measurements over trend-driven “vanity sizing,” aiming for true-to-size consistency across its collections. This commitment ensures customers can reliably select their appropriate size, minimizing returns and maximizing satisfaction.
However, the inherent nature of knitwear – a St. John signature – introduces a degree of flexibility. Knit fabrics possess natural stretch and drape, allowing for some accommodation in fit. Despite this, precise measurements remain crucial, particularly for structured pieces like jackets and coats.
St. John acknowledges a global customer base and provides comprehensive size conversions for France, Italy, the UK, and Japan. This dedication to inclusivity extends to offering a range of sizes, from XS to XL and beyond, catering to diverse body types. The brand encourages customers to utilize the official size guide and, when in doubt, to prioritize measurements over relying solely on familiar size labels. Ultimately, St. John’s philosophy is about empowering women to feel confident and beautiful in clothing designed to fit them perfectly.

Utilize this chart as a starting point, but always prioritize your individual measurements for the most accurate size selection. Consider consulting the detailed bust, waist, and hip charts for further guidance.
Bust Measurements and Size Correlation
Accurate bust measurement is paramount for achieving a flattering fit in St. John’s apparel, particularly knit dresses and tailored tops. Begin by measuring around the fullest part of your bust, keeping the tape measure level and comfortably snug – not tight. This measurement directly correlates to the appropriate size, as detailed below.
| Size (US Letter) | Bust Measurement (inches) |
|---|---|
| XS | 31-32 |
| S | 32-33 |
| M | 33.5-34.5 |
| L | 36-37 |
| XL | 38-39 |
If your measurement falls between sizes, we recommend sizing up for a more comfortable fit, especially in structured garments. Remember that St. John designs often feature a refined silhouette, so precise measurements are key. Always cross-reference with waist and hip measurements for a holistic fit assessment.
Waist Measurements and Size Correlation
Determining your accurate waist measurement is crucial for St. John apparel, influencing the fit of skirts, dresses, and tailored pants. Measure around your natural waistline – typically the narrowest part of your torso – ensuring the tape measure sits comfortably and isn’t constricted. Maintain a level position for the most precise reading. This measurement directly corresponds to the size chart below.
| Size (US Letter) | Waist Measurement (inches) |
|---|---|
| XS | 25-26 |
| S | 27-28 |
| M | 29-30 |
| L | 31-32 |
| XL | 33-34 |
If your waist measurement falls between sizes, consider the garment’s style. For more fitted styles, choose the smaller size; for relaxed fits, size up. Always compare your waist measurement with bust and hip measurements for a comprehensive fit assessment, ensuring a flattering and comfortable St. John silhouette.
Hip Measurements and Size Correlation
Accurate hip measurement is vital for achieving the perfect fit in St. John’s skirts, dresses, and pants. Measure around the fullest part of your hips and buttocks, keeping the tape measure level and comfortably snug – not too tight, nor too loose. Ensure your weight is evenly distributed for a precise reading. This measurement, alongside bust and waist, dictates the optimal size selection.

| Size (US Letter) | Hip Measurement (inches) |
|---|---|
| XS | 35-36 |
| S | 37-38 |
| M | 39-40 |
| L | 41-42 |
| XL | 43-44 |
If your hip measurement differs significantly from your waist or bust, prioritize the hip measurement for bottoms and dresses. For a streamlined look, consider tailoring if needed. Remember to consult the full size chart and consider the garment’s fabric and style for the most flattering St. John fit, ensuring both comfort and elegance.

Designer Conversion Size Chart Details
Understanding St. John’s designer conversion size chart is essential for a precise fit, as sizing can vary between brands and regions. This chart provides a detailed breakdown, bridging the gap between US standard sizes and international equivalents – France, Italy, and the UK.
The chart correlates US numeric sizes (0, 2, 4, etc.) with corresponding letter sizes (XS, S, M, etc.). Crucially, it links these to bust, waist, and hip measurements, offering a holistic approach to finding your ideal size. Note that these are general guidelines; individual garment construction and style can influence fit.
For example, a US size 6 typically converts to a French size 38, an Italian size 40, and a UK size 10. However, always prioritize your actual body measurements over relying solely on converted sizes. Referencing the detailed bust, waist, and hip measurements within the chart ensures a more accurate selection. St. John’s commitment to quality extends to providing a consistently flattering fit.
St. John Knit Dresses: Specific Sizing Considerations
St. John knit dresses, renowned for their luxurious feel and sophisticated designs, often require specific sizing attention. Due to the inherent stretch and drape of knit fabrics, a precise fit is paramount for achieving the signature St. John silhouette.
Consider the dress’s style – a body-con knit will demand a closer fit than a more relaxed, A-line design. Pay close attention to bust and hip measurements, as these areas are crucial for a flattering fit. While the knit offers some give, avoid relying on excessive stretch; a dress that’s too small will lack the intended elegance.
Review the garment’s specific measurements listed on the product page, not just the general size chart. If you’re between sizes, it’s generally recommended to size up, especially for more structured knit styles. Remember that the Pre-Fall 2025 Collection features iconic knit dresses, so accurate sizing is key to enjoying their timeless appeal.
St. John Jackets and Coats: Size Recommendations
St. John jackets and coats are investment pieces designed for enduring style and comfort. When selecting your size, consider layering – will you typically wear sweaters or heavier garments underneath? If so, opting for the next size up is advisable to ensure a comfortable range of motion.
Shoulder fit is particularly important in jackets and coats. A well-fitted shoulder seam should lie flat and not extend beyond your natural shoulder line. Pay attention to sleeve length; sleeves that are too short can detract from the overall polished look.
Refer to the detailed size chart, focusing on bust and waist measurements for a tailored fit. For coats with a more relaxed silhouette, you may find your usual size provides a comfortable fit even with layering. Explore the latest collection, including textured tweed options, and remember to consult product-specific measurements for the most accurate guidance.
How to Measure for St. John Apparel
Accurate measurements are key to finding your perfect fit with St. John apparel. Begin with the bust: measure around the fullest part of your bust, keeping the tape measure parallel to the floor. For waist measurement, find your natural waistline – typically the narrowest part of your torso – and measure around it comfortably.
To determine your hip measurement, stand with your feet together and measure around the fullest part of your hips, again ensuring the tape measure is level. It’s best to have a friend assist you for greater accuracy. Wear minimal clothing during measurements, or your usual undergarments.
Compare your measurements to the St. John size chart, noting the corresponding US, French, Italian, UK, or Japanese size. If your measurements fall between sizes, we recommend sizing up for a more comfortable fit. Remember to consult specific product details, as some styles may have unique sizing considerations.
Tips for Finding the Perfect Fit
Achieving the perfect fit with St. John apparel requires a little extra attention. Always refer to the official St. John size guide and compare your measurements carefully. Remember that sizing can vary slightly between different styles, particularly knit dresses, jackets, and coats.
Consider the fabric and silhouette of the garment. More structured pieces may require a closer fit, while flowing knits offer more flexibility. Don’t hesitate to read customer reviews for insights into how specific items run in size. If you’re between sizes, opting for the larger size often provides a more comfortable and flattering fit.
When shopping online, utilize the detailed product descriptions and size charts provided. If possible, visit a St. John boutique or authorized retailer for a professional fitting. A well-fitted garment enhances your confidence and showcases the luxury of St. John’s designs.

Common Sizing Issues and Solutions
A frequent concern with luxury brands like St. John is consistency across different styles. Knit dresses, for example, may have a more forgiving fit than structured jackets or coats. Variations can occur due to fabric composition and design details.
If you find a garment feels too snug, particularly in the bust or hips, consider sizing up. Conversely, if it feels too loose, especially in the waist, a size down might be more appropriate. Remember that St. John’s sizing can run slightly smaller than standard US sizes.
When in doubt, utilize the official size chart and carefully measure yourself. If purchasing online, review customer feedback for specific style insights. For jackets, consider shoulder width and sleeve length.
