If you've ever ordered a Reformation dress online, you know the anxiety of waiting for it to arrive. You checked the size chart, you measured yourself, and you thought you had it right. Then the package comes, and the fit is… not what you expected. That's because Reformation size 0 measurements are unique. They're not what you'd find at Zara or even Madewell. So let's break down exactly what they are and what they mean for your body.
What Are the Official Reformation Size 0 Measurements?
Reformation is transparent with their sizing. For a size 0, the official numbers are: bust 31.5 inches, waist 23.5 inches, and hips 34 inches. These measurements are based on a sample size that the brand uses for all their garments. But here's the catch: those numbers don't always translate to the same fit across every style. A size 0 in a stretchy knit dress will feel different than a size 0 in a structured linen top. The listed measurements are a starting point, not a guarantee. And if you're used to standard size 0 from other brands, these numbers might seem a bit snugger. That's because Reformation tends to cut their clothes closer to the body, especially in the hips and bust.
How Do These Measurements Compare to Other Brands?
To get a sense of scale, let's compare Reformation size 0 to a typical size 0 from brands like Everlane or Uniqlo. Those brands often list a size 0 with a bust around 32 inches, waist 24 inches, and hips 35 inches. That's half an inch larger in the bust and waist, and a full inch larger in the hips. So if you're a true size 0 at Everlane, Reformation's size 0 will likely feel tighter, especially if you have hips or a bust that's on the higher end of the spectrum. Conversely, if you're between sizes in other brands, you might find Reformation's size 0 fits like a 00 elsewhere. This is why checking the individual garment's size guide is critical—not just the brand's general chart.
Who Does the Reformation Size 0 Fit Best?
Given those numbers, Reformation size 0 is best suited for someone with a very straight or slightly defined waist, a smaller bust, and narrow hips. If you have a pear-shaped body like mine, you might find that the waist fits well but the hips feel restrictive. In that case, sizing up to a 1 or 2 might be necessary, even if you're usually a size 0. For those with a small frame and a more athletic build (less curve), this size could be a dream. The brand's aesthetic is often body-conscious, so if you prefer a looser fit, consider sizing up regardless of your measurements. I've learned that the hard way with a few ill-fated online orders.
How to Measure Yourself for a Reformation Size 0
To avoid disappointment, measure yourself exactly how Reformation does. Use a soft tape measure, and stand naturally. For bust, measure around the fullest part, keeping the tape parallel to the floor. For waist, find your natural waist (the narrowest part, usually above your belly button) and measure snugly but not too tight. For hips, measure around the widest part, typically 7-8 inches below your waist. Write down these numbers and compare them to the garment's specific size chart, not just the generic one. Some Reformation items include stretch, so look for fabric content—if it has spandex, you might get away with your usual size even if your measurements are slightly over. If it's 100% cotton or linen, go with the larger measurement.
Common Fit Issues and What to Watch For
The most common issues with Reformation size 0 are tightness in the hips and length. Reformation's dresses are often designed for taller frames, so if you're 5'4" or under, the hem might hit at an awkward spot. Check the model's height in the product photos and the garment's length measurement. Also, pay attention to the bust—if you're a 32C or larger, you may need to size up even if your waist is a 23.5. I've found that button-up blouses in size 0 can pull at the chest, while slip dresses can be surprisingly forgiving. Another tip: read reviews. Customers often mention how a specific style runs, and that's gold. A size 0 in the popular Odette dress fits differently than in the Farrah dress, even though both are listed as size 0.
Final Thoughts: Should You Buy a Reformation Size 0?
Yes, but only if you know your exact measurements and you're comparing them to the garment's specific chart. Don't rely on your usual size from other stores. If you're between sizes, order both and return one. Reformation's return policy is straightforward, and they offer free returns for store credit. For someone with a petite frame and minimal curves, the size 0 could be a perfect fit. For pear-shaped or bustier bodies, expect to size up. Comfort is not a compromise—it's an attitude. And that means knowing which size actually fits, not just what the tag says. So measure, compare, and don't be afraid to order a different size than you're used to. Your clothes should serve your body, not the other way around.
