Do Reformation Jeans Run Small? What a Size 28 (Actually 29) Wants You to Know

So you're staring at a pair of Reformation jeans online, wondering if they'll actually fit. I've been there. I'm a 28-year-old guy with a pear-shaped body and a small frame — and I've tried on seven different pairs of Reformation jeans over the past year. The short answer? Yes, do reformation jeans run small. But let me explain why, and more importantly, what you can do about it so you don't end up with a $200 pair of denim that sits in your closet unworn.

First, a quick reality check: Reformation jeans are cut for a very specific body type — typically someone with a straight waist and minimal hip-to-waist difference. If you have any curves or a bit of a belly, the standard sizing will likely feel restrictive. I usually wear a size 28 in most brands (Madewell, Everlane, Levi's), but in Reformation, I consistently need a 29 or even a 30 depending on the cut. That's a full size up, sometimes two. And I'm not alone — every friend I've asked has had to size up at least one.

Let's get into the why so you know what to expect.

The Short Answer: Yes, They Do

Reformation jeans are known for running about one to two sizes small. This isn't a secret — even their own website suggests sizing up if you're between sizes. The fabric plays a big part: they use rigid, non-stretch denim for most of their jeans, which means no give. If you're used to jeans with 2% elastane, stepping into 100% cotton Reformation jeans is going to feel like a different world. The waistband doesn't budge, the hips don't stretch, and if it's snug in the dressing room, it's not going to loosen up with wear.

I've learned this the hard way. My first pair, the Jane cut in a size 28, fit perfectly in the leg but I couldn't button the waist without lying down. I returned them and got a 29 — still tight but wearable after a few wears. By the end of the day, I usually have to unbutton them on the train ride home. Not ideal.

Why Reformation Runs Small (and Two Brands That Don't)

Reformation's whole thing is sustainability. They use deadstock fabric and produce in limited runs. That rigid denim? It's intentional — they want jeans that last and hold their shape. But that also means they don't account for the reality that most bodies aren't sample size. Compare that to Madewell, which uses stretch denim in almost everything. Madewell's size 28 fits me perfectly from day one with no break-in period. Everlane's jeans are also more forgiving, though they tend to be more consistent with sizing.

If you're used to stretchy jeans, do reformation jeans run small? Yes, noticeably. If you're coming from a brand like Levi's, which uses a mix of rigid and stretch, you'll still need to size up at least one. The only way around this is to check the specific cut — some styles like the Iris flare or the Dixie high-rise are known to run slightly larger, but I haven't found that to be reliable.

How to Find Your Right Reformation Size (Without Returning Everything)

Here's the system that works for me:

1. Measure your waist in inches where you actually wear your jeans (not your natural waist, but where the top of the jeans will sit). Reformation's size chart is actually pretty accurate if you go by inches, not size number.
2. Ignore their size chart's hip measurement — it always underestimates. If you have any hip, add 1-2 inches to whatever the chart says.
3. Order two sizes — your normal size and one size up. Returns are free, and you'll save yourself a trip to the store.
4. Wear them around the house for an hour before deciding. If they leave red marks, they're too small. If you can fit two fingers flat between your waist and the jeans, that's the right snugness.

For reference: I'm 5'10", 155 lbs, with a 31-inch waist and 39-inch hips. In Reformation, a size 29 fits comfortably in the waist but is tight in the thighs. Size 30 fits everywhere but needs a belt. Your mileage may vary.

The Bottom Line: Worth the Fuss or Skip?

If you love the look of Reformation jeans — the vintage washes, the flared cuts, the planet-friendly ethos — and you're willing to deal with sizing quirks, they're a good investment. Just plan to size up, expect a break-in period, and don't be surprised if you need to try two or three sizes. But if you want jeans that fit out of the box without the headache, stick with Madewell's stretch denim or Everlane's classic cuts. They won't have the same cult status, but your morning commute will be a lot more comfortable.

Comfort is not a compromise. It's an attitude. And honestly, I'd rather spend my mental energy on deciding if I want latte art than worrying about whether my jeans will button.

Quick Sizing Questions

Do Reformation jeans stretch out with wear? A little, but not much. Rigid denim has minimal give. If they're tight in the waist, they'll stay tight.

Should I size up for Reformation jeans? Almost always yes. Start with one size up from your usual.

What's the best Reformation cut for pear shapes? The Iris flare or the Camber straight — both have more room in the hip and thigh.

Can I wear Reformation jeans if I'm between sizes? Yes, but go with the larger size. You can always wear a belt.
