How Should a Silk Robe Fit?
A friend stopped by last summer wearing a silk robe she had owned for a decade. The sash was tied at the slightly lower waist where she actually preferred it. The shoulders sat where they sat. The hem moved with her without catching on anything. She did not look like she was wearing a silk robe so much as she was wearing the robe she always wore.
That is the answer to this question, more or less. A silk robe should fit the way a robe you have owned for ten years fits. The trick is knowing how to choose one that gets there on the first day rather than the third year.
A Short Answer for the Person Skimming
A silk robe should sit lightly on the shoulders without pulling, close at the chest with the sash at your natural waist, and fall straight from the shoulder to the hem without bunching at the back. The fit should feel as if the robe is resting on you, not gripping you. A silk robe is not a tailored garment. It is built to drape, not to fit close, which is why the same size can work across a range of bodies.
Tara Sartoria silk robes are made one piece at a time by master artisans in Vietnam's historic silk villages, finished with French seams, machine washable, and sized XS to 4XL as standard with custom sizing available when needed.
The Two Fit Points That Actually Matter
A silk robe only has to fit in two places. The shoulders, lightly, and the sash. Everything else is drape. This is the fact that makes silk robes the most forgiving silk piece to size, and it is also the fact most silk brands will not tell you, because telling you would make them sell fewer sizes per robe.
The shoulders should sit at or just past your natural shoulder line. If the shoulder seam is sitting halfway down your upper arm, the robe is one or two sizes too large. If the shoulder seam is pulling up toward your neck, the robe is too small. A small amount of overhang is correct. The robe is not a jacket. The shoulder should not feel structured.
The sash should close the robe comfortably at the waist with enough overlap in the front to feel modest when you sit down. The natural waist is where the sash sits best, slightly above the navel. Tying the sash lower is a style choice, not a fit problem. If you have to pull the sash tight to close the robe, the robe is too small. If the sash wraps almost twice around, the robe is too large.
Everything else, the chest, the hip, the inseam, does not need to fit precisely. The robe falls past these points without touching them in a structured way.
What Correct Fit Looks Like When You Put It On
The first thing you should feel when you put on a properly fitted silk robe is the weight of the fabric settling against your back and shoulders. It should feel substantial, not light. A robe that floats away from the body when you walk is too thin, regardless of size. A 27 momme silk robe sits down on the body in a way most silk does not, because the weight of the fabric is doing the work.
The shoulder seam should not press into your shoulder. It should sit on it. If you feel the seam at all, it is sitting in the wrong place.
The robe should close at the front with about four to six inches of overlap when sashed. Less overlap than that, the robe is too small for your frame. More than that, it is too large or you are wearing the wrong cut.
The hem should hang straight from the shoulders. If you see fabric bunching at the lower back when you stand straight, the robe is sitting too tightly at the shoulders. If the front panels separate while you walk, the sash is tied too loosely or the cut is wrong for the way you move.
What an Incorrect Fit Looks Like
The most common fit problem with silk robes is the robe being too small in the shoulders. The fabric pulls across the upper back, the front panels separate, and the whole garment feels tight. People often respond to this by sizing up two, which then makes the robe too large in the hem and the sleeves. The right answer is sizing up one, not two.
The second most common fit problem is the robe being too large overall. The robe was a gift, the size was a guess, the shoulders sit halfway down the upper arm, and the fabric pools at the back. This robe will get worn three times and folded away. If this is the robe you have, it is exchangeable for a smaller size. Customers can initiate that exchange directly without involving the gift-giver, which is one of the reasons we built the return process the way we did.
The third common problem is the sash. A sash that will not hold a knot for the day is almost always a sash made from too-thin fabric, which is a problem with the construction of the robe, not the size. A proper silk robe sash is a tube of doubled fabric, not a single layer. If your robe's sash slips loose by mid-morning, the robe is built to a cheaper standard.
How to Choose Your Size When Ordering Online
The Tara Sartoria size chart runs XS to 4XL as standard. The measurements on the chart are body measurements, not garment measurements. If you measure your chest at 36 inches, you read across to the size that includes 36 in its chest range, not the size whose garment chest is 36.
The general rule for silk robes is to size in line with the chart, not down. If you are between sizes, size up. The robe is built to drape, and a slightly larger size will drape more like the silk wants to drape. A slightly smaller size will pull at the shoulders and across the back. The asymmetric forgiveness is real: sizing up errs into a robe that still works, sizing down errs into a robe that does not.
For taller customers, the long robe will read slightly shorter on you. If you are over 5'10" and you want the long classic robe to fall at mid-calf rather than just below the knee, custom sizing is available when needed.
For customers between body shapes, choose by chest first, then by hip. The robe forgives waist variation the most.
How Fit Differs Between Men's and Women's Silk Robes
The women's silk robe is cut to fall lightly from the shoulder line with a natural waist sash and a relaxed hem. The cut is the same across sizes, scaled up or down. The drape is what changes the look on different bodies.
The men's silk robe is cut wider in the shoulders and the chest, with a longer arm length, and the hem falls in a straighter line. The sash sits slightly lower at the natural waist. The cut is built around the proportions of a fuller upper body and longer reach.
Customers sometimes ask whether a woman can wear the men's silk robe. The answer is yes, but the shoulders will be wider than necessary and the chest will be loose. If you want a more architectural drape, the men's robe in a smaller size is one approach. If you want the robe to look like the photographs, the women's cut in your true size is the right answer.

This is a general reference. The full size chart on the product page has body measurements for chest, waist, and hip across both men's and women's cuts. If you are between sizes, size up. If you have specific body asymmetries or fit preferences, write to us and we will help you decide.
The Takeaway
A silk robe should sit lightly on the shoulders, close comfortably at the chest with the sash at the natural waist, and fall straight from the shoulders to the hem. The robe is built to drape, not to fit close, which is why the same size works across a range of bodies. When in doubt, size up. The fabric is heavy enough to settle correctly even when the cut is slightly loose.

Frequently Asked Questions
How tight should a silk robe fit?
It should not feel tight at all. A silk robe should rest on the body, not grip it. The shoulders should sit lightly with a small amount of room. The robe should close at the chest with four to six inches of front overlap when sashed. The fabric should fall away from the body rather than hug it. If you feel the shoulder seam pulling, the robe is too small. If the shoulders sit halfway down your upper arm, it is too large.
Should I size up or size down for a silk robe?
Size up if you are between sizes. The robe is built to drape, and a slightly larger size will look correct on the body, while a slightly smaller size will pull at the shoulders and back. The cost of sizing up is a small amount of extra fabric. The cost of sizing down is a robe that does not work. The asymmetric risk makes the up-size the safer default.
How is the men's silk robe cut differently from the women's?
The men's robe is cut wider in the shoulders and the chest, with longer arms and a straighter hem. The sash sits slightly lower at the natural waist. The construction, fabric, and seam treatment are identical. The fit is what changes. Women can wear the men's cut for a more architectural look, but the shoulders will be wider than necessary for most women's frames.
What if my robe doesn't fit when it arrives?
Tara Sartoria offers free returns and exchanges within 30 days in the US. You can swap for a different size without paying for return shipping, and if it is a gift, the recipient can initiate the exchange directly. Custom sizing is available when needed for a small fee, especially for taller customers, customers above the standard 4XL range, or anyone with specific fit needs that the standard chart does not address.
What if my robe doesn't fit when it arrives?
Use a soft tape measure and measure your chest at the fullest point, your natural waist, and your hip at the fullest point. Read the measurements against the body measurements in the size chart, not against garment measurements. If your chest puts you in size L but your hip puts you in size M, choose the size that fits the chest. The robe forgives hip and waist variation more than it forgives chest variation.
