Levi's 501 Original Dark Blue, Straight Leg: How to Choose the Right Size and Avoid Mistakes

The Levi's 501 Original dark blue, straight leg jean charms with its iconic silhouette, classic fit and timeless denim spirit. Yet two models that look similar in a photo can feel very different once you try them on. Fabric, cut and size choice all deserve a bit of attention before you place your order.

Common Pitfalls Before Buying a 501 Jean

1. Confusing Straight Leg with Slim Fit

A straight leg jean for men should keep a fairly even line from the thigh down to the ankle. The 501 Original has a straight leg cut, with a classic amount of room through the hip and thigh. The Levi's 511, on the other hand, is closer to the body and is usually worn below the waist.

Don't rely solely on the model photo. Always check for "straight" or "slim" labels, the waist position and the stated leg width.

2. Mistaking Stretch Denim for a Non-Stretch Model

A non-stretch Levi's jean made from 100% cotton behaves very differently from a fabric that contains elastane. It offers a more structured feel, but you need to get the size right from the start. If you prefer a softer feel from the first wear, a 501 in stretch denim might suit you better. Its composition will be different, though.

3. Relying on Your Usual Size Without Taking Measurements

Levi's sizes are usually given in numbers, while French equivalents and letter sizes can vary from one product page to another. Here, a size 32 Levi's corresponds to a waist measurement of 81.3 cm and a hip measurement of 97.8 cm. These measurements should take priority over the habit of always ordering the same size.

The Criteria to Check Before You Buy

Fabric: 100% Cotton or Stretch Denim

The Levi's 501 Original Marlon Dark Wash featured here is made from 100% cotton and described as a non-stretch denim. It's aimed at those looking for a classic five-pocket jean with a button fly and a fabric that holds its shape well.

Other versions of the 501 have a different composition. The Medium Indigo Stonewash model, for example, combines cotton, polyester and elastane. It may feel softer, but it shouldn't be confused with a 501 jean in 100% cotton denim.

Cut and Waist Position

The 501 Original is worn at the waist, with a regular fit through the upper leg and a straight leg opening. This silhouette pairs easily with a t-shirt, shirt, sweatshirt or denim jacket.

The Marlon Dark Wash shade is a dark blue jean for men that's easy to wear every day. It works just as well with a smart-casual office outfit as it does with a simpler look and a pair of trainers.

Useful Measurements

To choose your size, measure your waist at the point where you want the trousers to sit, without pulling the tape measure tight. Then compare the result with the measurements on the product page:

  • Levi's 24: waist 61 cm, hips 77.5 cm, French equivalent 40.
  • Levi's 28: waist 71.1 cm, hips 87.6 cm, French equivalent 44.
  • Levi's 30: waist 76.2 cm, hips 92.7 cm, French equivalent 46.
  • Levi's 32: waist 81.3 cm, hips 97.8 cm, French equivalent 48.
  • Levi's 34: waist 86.4 cm, hips 102.9 cm, French equivalent 50.
  • Levi's 38: waist 96.5 cm, hips 113 cm, French equivalent 54.
  • Levi's 42: waist 106.7 cm, hips 123.2 cm, French equivalent 58.

With a non-stretch fabric, avoid choosing a very tight size hoping it will loosen up quickly. A comfortable fit at the waist and thighs is always better for walking, sitting or driving without discomfort.

Caring for Your Dark Blue Levi's Jeans

To preserve the colour and minimise shrinkage, turn the jeans inside out before washing and choose a cold cycle with similar-coloured items. Avoid bleach. Tumble drying is indicated on the product pages for these models, but a moderate temperature is best. If needed, iron the jeans on the reverse side.

Washing too often can speed up colour loss and wear out the fibres. Between machine washes, air the jeans and spot-clean small stains when that's enough. The sewn-in label on the garment is your best guide, so always check it for care instructions specific to the model you receive.

Frequently Asked Questions

Is the Levi's 501 Original dark blue stretchy?

The Marlon Dark Wash model featured in this selection is made from 100% cotton and described as non-stretch. It will therefore feel less flexible from the first wear than a jean containing elastane. For more freedom of movement, choose a version whose composition explicitly mentions a stretch fibre.

How do I choose the size of a Levi's 501 jean?

Measure your waist and hips, then compare them with the size chart on the product page. The 501 is worn at the waist, and its non-stretch fabric doesn't justify going down a size. If you're unsure, also check the returns policy before ordering.

How long can a 501 jean last?

Its lifespan depends on how often you wear it, the friction it's subjected to, and how you wash and dry it. Washing cold, inside out, with moderate and infrequent drying can help preserve the fabric and colour. However, it's impossible to guarantee a precise duration for every wearer.
