If you are searching for Dockers WPL 423 CA00342 straight fit to replace a favorite pair of pants, the next useful detail is the garment’s style number. WPL and CA numbers identify businesses for textile labeling; they do not identify one particular cut, color or fabric. A listing that repeats those numbers is not enough to establish that it matches your old trousers.
Start with photographs of all the inside labels, the waist and inseam, and the full front and back of the pants. This guide explains how to narrow the match and compares two identifiable Dockers straight-fit families when an exact replacement cannot be found. It is based on official product information and matching retail listings, without hands-on wear testing.
What the numbers on your Dockers label can tell you
| Label information | What it helps identify | What you still need |
|---|---|---|
| WPL 423 | A business identification used in textile labeling | Garment style, finish, size and fabric |
| CA00342 | A Canadian textile dealer identification | The actual product code and garment details |
| Style or product code | A much narrower product reference | Color or finish suffix and the correct size |
| Straight fit | A cut description | The specific product family, rise and measurements |
| Waist and inseam | The labeled size | Actual measurements if the pants are worn or altered |
The FTC’s textile-labeling guidance explains that an RN or existing WPL number can stand in for a company’s name. Canada’s Competition Bureau similarly explains that a CA number identifies the dealer in place of its name and address. These systems explain why the same identifier can appear on different garments.
Do not use WPL 423 or CA00342 to infer a production year, a particular fabric blend, D2 sizing or authenticity. They are useful label information, but none of those conclusions follows from the numbers alone.
How to find a closer replacement
- Open every layer of the care label. Check both sides and any small adjoining tag. Photograph the complete printed information rather than cropping down to WPL or CA.
- Look for a separate style or product code. Copy letters, digits, hyphens and suffixes exactly. Current Dockers pages show codes such as 398980006 for the black Workday Straight Fit model.
- Write down the product family. Workday, Ultimate and Signature identify different ranges. A straight leg in one family does not guarantee the same feel as another.
- Record the fabric composition and construction. Note the percentages on your own label, flat front or pleats, pocket layout, waistband and whether the pants have a pressed crease.
- Measure the pair you actually like. If you are buying used or discontinued stock, ask the seller to measure the same points rather than relying on a generic size chart.
A full style code is more useful than a search containing only brand and size. Search the full code first, then the style portion with “straight fit.” If the result is a different color, compare the complete code before buying. Keep an old order confirmation if you have one; it may record the exact retail description or size variant even after a paper tag has faded.
What Dockers means by straight fit
Dockers describes its straight-fit range as straight through the hip and thigh with a straight leg opening. Its fit selector distinguishes this from Classic, which is more generous through the hip and thigh, and Slim, which is slimmer in those areas. Several fit families can have a straight leg opening, so “straight leg” alone is not a complete match.
Older retail listings sometimes include D2 alongside Straight Fit. Treat that as a clue to the fit family, then check the style and measurements. Do not assume all D2 pants share one waistband, rise or fabric. Likewise, a Classic Fit listing should not be substituted just because the photograph shows legs that look straight.
Two straight-fit alternatives to compare
| Option | Verified example | Useful distinction | Check before ordering |
|---|---|---|---|
| Workday Khaki Smart 360 Flex | Black (Stretch), standard 34W x 32L | Wrinkle-resistant office-oriented khaki with a flexible waistband | Model family 39898 and the selected fit |
| Ultimate Chino Smart 360 Flex | New British Khaki (Stretch), standard 34W x 32L | Casual chino with four-way stretch and a hidden security pocket | Model family 84467 and the garment’s own fiber label |
Dockers Workday Khaki Smart 360 Flex
The official black Workday Straight Fit page identifies style 398980006, a 93% cotton and 7% elastane fabric, four-way stretch, a flexible waistband, front slant pockets, back welt pockets and a hidden security pocket. Dockers describes the fabric as wrinkle-resistant and gives cold, delicate-cycle machine-washing instructions.
This is a sensible comparison point for someone seeking a neat everyday office khaki with stretch. It is not established as the exact replacement for a pair labeled only WPL 423 CA00342. The linked retail variant is standard 34W x 32L in Black (Stretch); choose your own size after checking the current selection.

Dockers Ultimate Chino Smart 360 Flex
The official Ultimate Chino Straight Fit page identifies style 844670000 in the khaki color family. It lists four-way stretch, a flexible waistband, a zip fly and a hidden security pocket. This makes it another relevant starting point if you want a casual chino rather than choosing solely by an old label number.
There is a fabric-description difference worth checking: the current manufacturer page separates its cotton content into 75% cotton and 20% recycled cotton, plus 5% elastane. The matching Amazon family lists 95% cotton and 5% elastane without that recycled-content breakdown. Do not assume an older retail pair has the same recycled content; use the label on the actual garment. The linked variant is standard 34W x 32L in New British Khaki (Stretch).
Measurements that help when the original style is discontinued
Lay the old pants flat, fasten the waist, smooth the fabric without stretching it and compare like-for-like measurements. A used pair may have been hemmed or changed shape through wear, so the tag is only one piece of information.
- Waist: compare the flat waistband measurement, using the same relaxed method on each pair.
- Inseam: measure from the crotch seam to the hem along the inside leg.
- Front rise: measure from the crotch seam to the top of the front waistband. This helps explain why two pairs with the same waist size sit differently.
- Thigh and leg opening: ask for the same measurement location on both pairs. A seller’s “thigh width” is hard to compare if the measuring point is unspecified.
- Alterations: look for a shortened hem, replaced waistband or tapered legs before assuming the original factory fit explains everything.
For a new pair, try sitting, walking and bending before removing tags or arranging alterations. Check the return terms for the particular seller and item, especially for used or clearance clothing. Do not wash a pair solely to see whether it shrinks into the right fit.
Frequently asked questions
Can I order identical pants using WPL 423 CA00342?
No exact garment match can be established from those identifiers alone. Add the style code, fit, color, waist, inseam and fiber content. Clear tag photos are especially helpful when asking a seller to identify older stock.
Does straight fit mean the same as classic fit?
Dockers treats them as different fits. Its current selector describes Classic as more generous through the hip and thigh. Both descriptions can include a straight leg opening, which is why the full fit name matters.
Should I buy my usual size in a newer style?
Use it as a starting point, then compare the new style’s chart and try-on fit. Different rise, stretch and waistband construction can change how the same labeled size feels. A favorite pair that has been altered is a particularly poor basis for assuming an identical off-the-rack fit.
Which option is closest to an older non-stretch pair?
Neither stretch option here is guaranteed to reproduce the feel of a non-stretch original. If matching the fabric is essential, search the original style and composition rather than accepting a similarly colored stretch chino.
