RRL Low Straight One-Wash Selvedge Denim: First Wash Review, Measurements & Fit Restoration Data

Hello, this is Lislab . For any denim enthusiast, there is always a quiet thrill in breaking in and caring for a favorite pair of jeans. Today, I’d like to share the first wash process, before-and-after measurement data, and subsequent wear updates for my RRL Low Straight One-Wash Selvedge Denim —a pair I’ve been documenting right here on my blog. Generally, one-wash, sanforized denim carries little stress when it comes to washing. However, as wears accumulate, proper timing becomes essential to reset the fabric’s tension and restore the silhouette from inevitable wear-stretching. Rather than aiming for drastic shrinkage or rapid fading, this first wash was focused entirely on tidying up the stretched waist, knees, and rear seat area. While some time has passed since the actual washing took place, I’ve included both the immediate post-wash data and the real-world evolution observed after putting another 40+ wears on them since.   

[Review] A.P.C. Petit New Standard Selvedge Raw Denim: The Perfect Fit After the Pain

Hello, this is Lislab.

A.P.C. is always at the center of the conversation when it comes to the best entry-level raw denim. Even among countless reproduction brands, its unique cool sheen and clean silhouette keep A.P.C. in a league of its own.

I remember being captivated by the silhouette and the iconic red selvedge line of A.P.C. back when it first led the raw denim trend. At that time, I preferred a relaxed fit and chose Naked & Famous instead. However, as I begin this new journey with Lislab, I’ve finally brought home the Petit New Standard to fully experience the brand I've always had my eye on.

The A.P.C. Petit New Standard is impeccably clean. The indigo hue is deep and luxurious, while the crisp Red Selvedge ID and Orange Stitching provide subtle, elegant accents. Its minimalism—even omitting the iconic leather patch—completes the sophisticated A.P.C. look.

The signature silver buttons and rivets exude a quiet premium feel, and the cleanly finished inner pockets prove that "less is truly more."



02. Sizing

"The Memory of the First Day (Buttons Near Bursting)"

<A.P.C. Petit New Standard Size & Measurement Chart>

* This data is a recompiled average by Lislab, based on A.P.C. official guides and measurement data from global premium denim retailers. Please note that raw denim may have slight individual variations; use these figures as a reference point for your size selection.


The most common advice you'll find for A.P.C. is to "size down." This is due to the unique nature of the fabric.

A.P.C. denim is Sanforized, so you don't have to worry about extreme shrinkage (turning into "children's clothes") after a wash. However, the dramatic "stretch" that happens as it molds to your body is the true signature of this brand.

Trusting my own data, I chose my True Size (30). The first wear felt like 100% cotton skinny jeans with zero stretch. The buttons barely closed, but it wasn't unwearable. While the new product is tagged at a 39.5cm waist(flat), it felt like a tight 39~39.5cm in real-time pressure.

03. The 3-Week Change

"Aging Proven by Data"

Here is the change in actual measurements after 12 wears over 3 weeks:

  • Waist: 39.5cm > 40.5cm (1cm increase)

  • Front Rise: 23.5cm > 25.5cm (2cm increase)


The waist stretch is remarkably visible. Compared to most denim that stretches only 0.5–1cm slowly, A.P.C.’s 1-2cm stretch is truly exceptional. This data is exactly why people recommend going true to size or sizing down.

While it doesn't feel like a stiff "armor" like LVC Rigid, the unique crispness of A.P.C. wraps around the legs perfectly. The fabric has now begun to "remember" my hip line and movements, making the fit much more flexible and comfortable than on Day 1.

Since I spend most of my work hours sitting, the Whiskers at the crotch and Honeycombs behind the knees have set in sharply, with the indigo beginning to rub off into a vibrant blue. I am already excited to see the high-contrast fades after the first wash.



Closing: Pain is Temporary, Fit is Forever


The A.P.C. Petit New Standard is the ultimate choice for those with a slender build seeking a sophisticated fit. The initial stiffness and tightness are simply part of the process.

The low rise allows it to sit perfectly on the hips, creating a silhouette that makes the legs look longer and keeps the seat looking sharp.

After three weeks, these jeans have molded to my body and are becoming my favorite "daily driver." I highly recommend them to anyone starting their denim journey.

Thank you for reading this long journey.

Sincerely, Lislab
