Knox Rose Flare Jeans – High-Rise Vintage-Inspired Denim
Our Knox Rose flare jeans bring back the retro silhouette you love with a modern stretch-denim upgrade. Designed with a high-rise waist that sits comfortably at your natural waistline, these jeans feature a fitted hip and thigh that opens into a full flare from the knee down—elongating your legs and balancing your frame.
We craft each pair from premium cotton-blend denim with just enough stretch to move with you through your day. The vintage-inspired washes range from classic dark indigo to sun-faded light blue, giving you over 20 versatile options to match your personal style. Pair them with a tucked-in blouse and platform sandals for effortless boho-chic, or dress them down with a graphic tee and sneakers for weekend errands.
Our flare jeans hold their shape wear after wear, thanks to reinforced belt loops and double-stitched seams at every stress point. The five-pocket styling includes functional front and back pockets sized to carry your essentials without adding bulk.
- High-rise fit: 10.5-inch front rise sits at natural waist
- Full flare leg opening: 20-inch hem circumference for balanced proportion
- Premium stretch denim: 78% cotton, 20% polyester, 2% spandex
- Inseam options: Regular 32-inch and Long 34-inch available
- Classic five-pocket styling with functional back pockets
Denim Fabric & Construction

We source premium cotton-blend denim for every pair of Knox Rose flare jeans, blending natural cotton fibers with performance stretch for all-day comfort. Our signature fabric contains 20% polyester for shape retention and 2% spandex for four-way stretch that moves with your body without bagging at the knees or seat.
Each pair undergoes a multi-stage washing process to achieve our vintage-inspired finishes—from light sun-faded washes to deep indigo rinses. We use enzyme washes and hand-sanding techniques on select styles to create authentic worn-in areas at the thighs and knees. The result is denim that looks like a treasured thrift-store find but performs like modern technical fabric.
Sizing & Fit Guide

Knox Rose flare jeans are designed to fit snugly through the waist, hip, and thigh, then flare from the knee down for a balanced silhouette. Our high-rise styles feature a 10.5-inch front rise that sits at your natural waist, while mid-rise options measure 9 inches for a more relaxed fit at the hips.
We offer regular and long inseam options across our core styles—32-inch regular works for most heights from 5’4″ to 5’8″, while our 34-inch long inseam accommodates taller frames or those who prefer extra length for heels. Our cropped flare measures 28 inches and hits at the ankle bone on average height.
Styling Your Flare Jeans

Knox Rose flare jeans pair beautifully with the rest of our boho-inspired collection. Tuck in a flowy peasant blouse to emphasize the high waist and create an elongated line from waist to hem. For casual days, try a cropped graphic tee or fitted tank that ends right at your natural waist—this proportion showcases the flare silhouette without cutting your frame in half.
Footwear makes or breaks the flare jean look. We love pairing our full-length flares with platform sandals, block-heel mules, or wedge espadrilles that add height and prevent the hem from dragging. Our cropped flare works with virtually any shoe—try white sneakers for weekend errands, strappy sandals for dinner, or ankle boots when temperatures drop.

What people are saying





Common questions about Knox Rose flare jeans
Knox Rose flare jeans run true to size and are designed to fit snugly through the waist, hip, and thigh with a full flare from the knee down. Our high-rise styles sit at your natural waist with a 10.5-inch front rise, while mid-rise options measure 9 inches. The stretch denim provides about a half-inch of give in the waist after a few hours of wear.
If you're between sizes, we recommend sizing up for comfort. The fabric will conform to your body after the first wear while maintaining its shape throughout the day.
Our regular 32-inch inseam works best for heights from 5'4" to 5'8" and is designed to reach the floor when worn with heels or platform shoes. If you're 5'9" or taller, choose our long 34-inch inseam option for proper coverage. For petites under 5'4", our cropped flare with a 28-inch inseam hits at the ankle bone and never drags.
The flare leg opening measures 20 inches in circumference on full-length styles, accommodating boots and platform footwear easily.
Yes, you can tumble dry Knox Rose flare jeans on low heat, though we recommend air-drying when possible to extend the life of the stretch fibers. High heat can break down the spandex over time and cause shrinkage in the cotton. Always wash your jeans inside-out in cold water to preserve color and stretch.
For best results, remove jeans from the dryer while slightly damp and hang to finish drying, or steam out any wrinkles on the reverse side once fully dry.
Knox Rose flare jeans contain 2% spandex for four-way stretch and 20% polyester for shape retention. You may notice about a half-inch of give in the waistband after several hours of wear, but the fabric recovers its original fit overnight or after washing. The denim won't bag at the knees or seat thanks to our recovery-stretch blend.
For the most consistent fit, wash your jeans every 4-6 wears or when the waist feels looser than you prefer.
Our classic high-rise flare features a 10.5-inch rise, 32 or 34-inch inseam, and 20-inch hem opening. The mid-rise flare with raw hem sits lower at a 9-inch rise for a more casual fit. Our cropped flare keeps the high-rise waist but shortens the inseam to 28 inches with an 18-inch hem opening.
All three styles share the same fitted hip-and-thigh silhouette that flares from the knee down, just with different rise heights and leg lengths to suit your preference and styling needs.
We offer over 20 vintage-inspired washes across our flare jean collection, ranging from crisp white denim and light sun-faded blue to classic medium indigo and deep dark rinses. Select styles feature hand-sanded distressing, enzyme washes, and raw hems for authentic lived-in character.
Wash availability varies by style and season—check each product page for current options, or visit our complete denim collection to browse all available washes.
Absolutely! Knox Rose flare jeans pair beautifully with ankle boots, especially our cropped flare style designed to hit right at the ankle bone. For full-length flares, tuck the hem into tall boots or let the flare drape over ankle boots—the 20-inch leg opening provides enough room to accommodate most boot shafts without bunching.
For the sleekest look, choose boots with a slight heel to prevent the hem from dragging and maintain the leg-lengthening effect of the flare silhouette.
