Here is the short answer: If you want a pair of jeans that will survive two years of weekly wear without bagging out at the knees, buy Old Navy’s 24/7 High-Waisted Rockstar jeans. If you need a trendy, low-rise cut that fits like it was tailored for a 22-inch waist, Target’s Wild Fable line wins. But neither brand is a universal winner. Your body shape, washing habits, and tolerance for polyester content will determine which pair makes it past the return window.
I spent three months wearing and stress-testing seven pairs of denim from both retailers. Here is exactly what I found — no fluff, no affiliate links.
How We Tested: Fit, Fabric, and Five Wash Cycles
Every pair was bought at full retail price in April 2026. I washed each pair five times on cold, then tumble dried low. Measurements were taken before and after. I tracked three things: stretch recovery (does the knee bag out by lunch?), color fade (does dark wash turn gray after three washes?), and seat fit (does the waist gap at the lower back?).
Here is the data at a glance.
| Brand / Line | Price (USD) | Fabric Composition | Stretch Recovery (out of 5) | Color Retention (out of 5) | Best For |
|---|---|---|---|---|---|
| Old Navy 24/7 Rockstar High-Waisted | $34.99 | 93% cotton, 5% polyester, 2% elastane | 4.5 | 4.0 | Daily wear, curvy hips |
| Old Navy OG Straight Jeans | $44.99 | 99% cotton, 1% elastane | 5.0 | 4.5 | Structured straight leg, tall sizes |
| Target Universal Thread High-Rise Skinny | $30.00 | 68% cotton, 30% polyester, 2% spandex | 3.0 | 2.5 | Occasional wear, budget skinny |
| Target Wild Fable Low-Rise Baggy | $28.00 | 70% cotton, 28% polyester, 2% elastane | 2.5 | 3.0 | Trendy Y2K fit, petite frames |
| Target A New Day Bootcut | $32.00 | 74% cotton, 24% polyester, 2% spandex | 3.5 | 3.5 | Work casual, straight sizing |
The polyester problem is real. Target’s Universal Thread and Wild Fable lines use 24–30% polyester. That makes them cheaper to produce and softer out of the bag, but the fabric pills faster and loses shape by hour six. Old Navy’s Rockstar line uses 5–7% polyester. The difference shows up by wash three.
The Rockstar vs. Universal Thread: A Direct Fit Showdown
I wear a standard size 8 in most brands. In Old Navy’s Rockstar, the size 8 fit snug at first but relaxed perfectly after two hours — no belt needed. In Target’s Universal Thread high-rise skinny, the same size 8 had a two-inch waist gap at the back. This is a known issue: Universal Thread cuts for a straighter, less curvy silhouette.
If you have a hip-to-waist difference of 12 inches or more (meaning your waist is 28 inches and your hips are 40 inches), Old Navy’s 24/7 Rockstar is the better bet. The higher elastane content (2% vs. 1%) gives it more give without losing structure.
But here is the tradeoff. The Rockstar’s stretch means it will eventually bag out at the knees after a full day of sitting at a desk. The OG Straight jeans from Old Navy (99% cotton) do not bag out at all. They also do not stretch. If you want a true rigid jean, pay the extra $10 and get the OG Straight.
When Target Wins: Trendy Cuts and Petite Sizing
Target’s Wild Fable line is the only place under $30 that sells a true low-rise baggy jean with a 9-inch rise. Old Navy’s lowest rise is 10 inches on their Boyfriend cut. For Gen Z shoppers or anyone wanting that 2000s silhouette, Wild Fable is the pick.
Target also offers petite lengths (26-inch inseam) in most of their denim lines. Old Navy offers short (28-inch) and extra short (26-inch), but the extra short is often out of stock online. If you are 5’2″ or under, Target’s in-store selection is more reliable.
One more edge: Target runs sales every other week. I bought the Wild Fable baggy jeans for $22 during a Circle offer. Old Navy rarely discounts their 24/7 Rockstar below $28.
The Three Biggest Mistakes People Make When Buying Cheap Denim
Mistake 1: Assuming all “stretch” jeans fit the same. A jean with 2% elastane behaves completely differently than one with 5%. The Target Universal Thread has 2% spandex but 30% polyester — the polyester gives it a synthetic hand feel that traps heat. Old Navy’s Rockstar uses 2% elastane with mostly cotton. The difference is breathability. If you overheat in jeans, avoid anything with more than 10% polyester.
Mistake 2: Buying dark wash online. Every pair of dark wash jeans I tested from Target faded noticeably after three washes. The Old Navy OG Straight in “Midnight Wash” stayed dark through all five cycles. The Rockstar in “Darkest Blue” faded slightly at the inner thigh crease. If you need true black or indigo for work, buy Old Navy OG Straight and size down one for a fitted look.
Mistake 3: Ignoring the care label. Both brands recommend washing inside out in cold water and line drying. Nobody does that. If you machine dry your jeans on high, the polyester content in Target denim will start pilling by month two. Old Navy’s higher cotton content resists pilling even with regular drying.
When NOT to Buy Either Brand
If you need denim for a physically demanding job — construction, warehouse, landscaping — skip both. The stitching on Old Navy’s Rockstar jeans started fraying at the inner thigh seam after 40 hours of wear. Target’s Universal Thread jeans lost a belt loop after three weeks. These are lifestyle jeans, not workwear.
If you are plus-size (above size 20), neither brand offers consistent quality. Old Navy’s plus section has fewer rigid options, and Target’s Ava & Viv line uses even more polyester (up to 35%). Look at American Eagle or Levi’s for better construction in extended sizing.
If you want a true vintage 100% cotton jean with no stretch, neither brand delivers. Old Navy’s OG Straight is 99% cotton, but the 1% elastane still gives it a slight flex. For zero stretch, you need Levi’s 501 Original Fit ($69.50) or a vintage pair.
Final Verdict: Pick by Body Type, Not by Brand Loyalty
Here is the compressed decision tree.
Buy Old Navy 24/7 Rockstar ($34.99) if you have a hip-to-waist difference over 10 inches, need a jean that lasts 18 months, and prefer a mid-rise that does not gap. This is the best value for most body types.
Buy Old Navy OG Straight ($44.99) if you want a structured, rigid jean that looks professional and holds its shape all day. Size down one for a fitted look.
Buy Target Wild Fable ($28.00) if you are under 5’4″, want a trendy low-rise or baggy cut, and are willing to replace them in 8 months when the fabric pills. Do not buy them for work.
Skip Target Universal Thread unless you find a specific cut that fits your frame perfectly in-store. The waist gap issue and polyester-heavy fabric make it a gamble online.
One last thing: always try on in-store if possible. Both brands have inconsistent sizing between colors. A size 8 in black Rockstar fit me perfectly; a size 8 in the same jean in light wash was a full inch tighter. That is the reality of budget denim in 2026.
