Our Keep Up Flare Jeans are the stretchiest pair we carry. Their page calls the material mega stretch and says they give you the comfort of leggings with the style of premium denim.
Our Fiona Bell Bottom Flare Jeans are made with super stretch denim that smooths and contours to your body, and they come in the widest size range we offer, XS through 1XL.
We describe stretch in words rather than percentages, so mega stretch, super stretch and stretch denim blend are the labels to compare, not numbers on a tag.
A high rise helps when your thighs need the room: sizing up in a straight leg leaves slack at the waist, while a high-rise flare holds the waist and lets the leg do the work.
For festival fashion and western concert outfits, pair flare jeans with platform boots and a graphic tee under an oversized shacket.
Hey Girl! If your thighs need the most give, reach for our Keep Up Flare Jeans at $59.99. Their page describes the material as mega stretch, which is the strongest stretch wording we use on any pair. If you want a wider size range or more colors, our Fiona Bell Bottom Flare Jeans at $49.99 are made with super stretch denim and run XS through 1XL in 26 colors.
Why a High-Rise Flare Suits Thicker Thighs ✨
A flare is cut close through the hip and thigh and then opens out from the knee, so the room you need sits where you need it and the leg balances the rest. The usual problem is not your shape, it is what happens when you size up in a straight leg to get thigh room: you end up with slack at the waist you did not ask for. A high rise helps because it holds at the narrowest part of your torso while the thigh sits comfortably. Every pair below is cut high rise, so the choice comes down to how much stretch you want and which size run fits you.
How Our Stretch Wording Compares 🌸
The denim industry usually talks about stretch as an elastane percentage, where roughly one to two percent is everyday give and three to five percent is the high-stretch tier. We do not print those percentages on our product pages. What we do instead is name the stretch, so here is how our wording lines up across the pairs with the most give through the leg.

Keep Up Flare Jeans, Our Stretchiest Pair
A Willow exclusive at $59.99, built with mega stretch material that contours, moves and flatters. Its page promises the comfort of leggings with the style of premium denim, which is exactly what you want when the thigh is the tight spot. You get a high rise fit, a dramatic flared silhouette, a frayed hem, functional pockets and the V-Cross waistline detail, on a 33.5-inch inseam in sizes 0/23 through 15/31, in Acid Wash and Dark Wash.
Fiona Bell Bottom Flare Jeans, the Widest Size Run
At $49.99, Fiona is made with super stretch denim that smooths and contours to your body while keeping a durable, high-quality feel. It pairs a high-waisted fit with a butt-lifting detail and a classic flare ankle on a 34-inch inseam, and it runs XS through 1XL across 26 colors, which is the broadest size and color range we carry. If you sit between our numeric junior sizes, the letter sizing here is often the easier fit to land.
Stretch is only half of it. What matters by the evening is recovery, meaning whether the denim comes back to shape instead of going slack at the knee and seat. The industry benchmark is a recovery rate of eighty percent or better after the fabric is stretched. You cannot read that off a label, so test it in the room: pull the fabric gently across the thigh and let go, and it should snap back rather than stay stretched. Then sit down, stand up and check the knees and the waistband have not given up. To keep that recovery, wash in cold water with a mild detergent and skip the hot dryer, because high heat degrades the elastic fibres over time.
Getting the Size and Length Right 🎉
Our two size systems trip people up more than the stretch does. Fiona uses letter sizes from XS to 1XL, while Keep Up, Lainey and most of our denim use numeric junior sizing like 0/23 or 9/28, where the first number is the junior size and the second is the waist in inches. If you know your waist measurement, the numeric run is the quicker path. Check our size charts before ordering, and if you are between sizes on a stretch pair, sizing up costs you less comfort than sizing down.
You can compare every run side by side in our size charts. For festival fashion and western concert outfits, these all work with platform boots and a graphic tee under an oversized shacket.
Which of your jeans has the most stretch for my thighs?
Our Keep Up Flare Jeans at $59.99. Their page describes the material as mega stretch, which is the strongest stretch wording we use, and promises the comfort of leggings with the style of premium denim.
Do you list the elastane or spandex percentage?
We do not print fabric percentages on our product pages. We name the stretch instead, so compare our wording: mega stretch on the Keep Up, super stretch denim on the Fiona, and a stretch denim blend on the Lainey.
Why do my jeans fit my thighs but gap at my waist?
That usually happens when you size up in a straight leg to get thigh room, which adds width at the waist you did not need. A high-rise flare holds at the narrowest part of your torso while the leg gives you the room, so the gap does not open up.
Which pair should I pick if I am between sizes?
Our Fiona Bell Bottom Flare Jeans, because the XS to 1XL letter sizing gives you more room to land than a numeric junior run. On any stretch pair, sizing up is the safer call than sizing down.
How do I keep stretchy jeans from going baggy?
Wash them in cold water with a mild detergent and hang them to dry. High dryer heat is what breaks down the elastic fibres, and that is what causes the sag at the knees and seat.
Do you have anything shorter than a full-length flare?
Yes, our Macy Ankle Bootcut at $36.99 is made from premium stretch denim with a 28.5-inch inseam and a 10-inch rise, so it finishes above the shoe if a full-length hem is too long on you.
