Vintage Size & Fit Guide
Great style begins with the right fit. Whether you are choosing a vintage original, a pre-loved find, or a contemporary piece, let the garment’s measurements lead.
The label is a starting point
Sizing varies across eras, brands, and silhouettes. A vintage label is not a reliable equivalent to a modern size, and previous alterations or wear can affect fit. Use the listed garment measurements rather than a universal size conversion.
Compare with a piece you love
Choose a similar garment that fits you well. Fasten it, lay it flat on a smooth surface, and gently smooth it without stretching. Use a flexible tape and compare like with like: jeans with jeans, a blouse with a blouse, and outerwear with a layer that accommodates what you wear underneath.
Flat width and full circumference are different measurements. Double a flat bust, waist, or hip width only when comparing it with a full-circumference figure. Do not double rise, inseam, shoulder, sleeve, or garment length. If a listing does not make its measurement convention clear, ask us before ordering.
Filled pre-owned example: Paul KC Yellow & Taupe High-Low Dress
Labeled size: Small. These measurements apply only to this individual Paul KC colorblock cutout dress, not to every size Small. All measurements are supplied garment measurements in inches, not body measurements.
| Size | Bust | Front length | Back length |
|---|---|---|---|
| Small | 30 inches; stretch jersey bodice | 32 inches | 49 inches |
The dress’s measurements were supplied under flat-lay notes. The 30-inch bust is reproduced as listed, without doubling it or converting it into a width. Its flat-width versus full-circumference convention has not been confirmed for this dress. Maximum stretch, waist, and hip measurements are not available. Contact us if you need clarification before choosing your fit.
Compare with a similar high-low dress you own, checking the front and back lengths separately. The stretchy bodice does not establish a maximum bust measurement.
Filled vintage example: 1980s Gallery Down Maxi Coat
This example uses the measurements supplied in our vintage Gallery coat listing, labeled Women's Large. These figures apply to this individual coat only, not to every vintage size Large. All measurements below are in inches.
| Measurement | Listed coat measurement | How to compare |
|---|---|---|
| Bust / chest | 38 inches full circumference | Compare with the full chest circumference of a similar coat you own. If measuring your coat flat from underarm to underarm, double that width before comparing with 38 inches. Do not double the listed 38-inch measurement. |
| Total length | 48 inches | Compare with the length of a similar coat you own, using the same measuring points. |
| Sleeve length | 24 inches | Compare shoulder seam to cuff, confirming that the listing uses the same method. |
| Shoulder to shoulder | 16.5 inches | Compare across the back between shoulder seams. |
| Waist / hips | Not supplied | Contact us if these measurements are important to your fit. |
The 38-inch bust is the coat’s full circumference, not a body measurement. Allow room for movement and winter layers when comparing with a coat that fits you well.
Measurement reference for other vintage pieces
Each product description contains that individual garment’s available measurements. The shared guide does not automatically change to match the product you came from. Compare your own garment with the measurements in the relevant listing.
| Measurement | How to measure your garment | Use for |
|---|---|---|
| Bust / chest | Straight across from underarm to underarm; note flat width or doubled circumference. | Tops, dresses, jackets and coats |
| Waist | Across the waistband or garment waist, relaxed; note flat width or doubled circumference. | Trousers, skirts, dresses and fitted garments |
| Hips | Across the fullest hip area; use the same position on both garments and note the measurement convention. | Trousers, skirts, dresses and fitted coats |
| Front rise | From the crotch seam up the front to the top of the waistband. | Jeans, trousers and shorts |
| Inseam | From the crotch seam along the inside leg to the hem. | Jeans and trousers |
| Shoulder | Across the back from one shoulder seam to the other. | Tops, jackets and coats with shoulder seams |
| Sleeve | From the shoulder seam to the cuff, following the sleeve. | Long-sleeved tops, jackets and coats |
| Garment length | For tops and coats, from the high shoulder beside the neckline to the hem; for trousers, from the top of the waistband down the outer leg. Follow any method specified in the listing. | Compare similar garment types |
Where to find each piece’s measurements
Check the product description for “Measurements,” “Size & Measurements,” or “Size Chart.” Match the chart row to the size you are considering. A chart may include sizes that are not currently available to select.
A little room makes the difference
Garment measurements are not body measurements. Consider the fabric’s stretch, the intended silhouette, and room for movement or layering. Measurements are approximate, not a guarantee of fit. If a measurement is missing or unclear, contact Thirteen Vintage before ordering. A considered comparison is always better than guessing from the label.
