Underwear Buying Guide: Prioritising Comfort and Durability

Choosing underwear? It seems simple, but in reality, it's often a minefield. Between fabrics that lose their shape after the second wash, seams that scratch, and marketing promises that don't hold up, it's easy to make the wrong choice. As the Head of Product Selection at Joybuy, I'm here to separate fact from fiction for you. Follow this guide to never again sacrifice comfort, style, or durability.

The 3 Pitfalls to Avoid When Buying Underwear

Before you fill your basket, keep these common mistakes in mind that can turn a simple purchase into a disappointment.

  1. The "100% Cotton" Myth: We agree, cotton is soft and breathable. But 100% cotton underwear also guarantees a fabric that will stretch and lose its shape at lightning speed. Without a touch of elastane (even just 5%), the support quickly becomes unreliable, and comfort fades as the hours go by.
  2. Forgetting the Waistband and Seams: An elastic band that digs into your waist, thick seams that leave red marks... Sound familiar? This is the hallmark of low-quality underwear. It might seem like a minor detail at the time of purchase, but it makes a garment simply unwearable for daily use.
  3. Buying Period Underwear Blindly:Period underwear is a revolution, provided you choose it wisely. Not all models are created equal. Ignoring the absorption level (light, medium, heavy flow) or the quality of the fabrics means risking leaks and unpleasant surprises.

The Criteria That Make All the Difference

To avoid making the wrong choice, focus on these two fundamental aspects: the material and the cut.

Fabric Composition: The Secret to Lasting Comfort

The material is the number one criterion for comfort that lasts. Here are the most common options:

  • Stretch Cotton: A reliable choice for everyday wear. A blend of 90% to 95% cotton and 5% to 10% elastane is the holy grail: the softness and breathability of cotton, combined with the essential elasticity for support and longevity.
  • Modal or Bamboo Viscose: Known for their incredible softness and moisture-wicking properties (often better than cotton), these materials are a dream for sensitive skin or for anyone seeking a more premium feel.
  • Synthetic Fabrics (Nylon, Polyester): Favoured for sports or fine lingerie, they excel in elasticity and are quick-drying. A crucial point: the gusset (the lining in the intimate area) must be made of cotton to ensure good hygiene.

The Cut: A Matter of Body Shape and Use

Whether you're a man or a woman, the cut determines both comfort and aesthetics.

  • For Men: The men's boxer brief (or trunk) remains the clear favourite, offering excellent support without compression. Briefs provide maximum support, while looser-fitting boxers are often reserved for nighttime or relaxing.
  • For Women: The range is wide: from the women's thong, invisible under a fitted outfit, to the classic brief for absolute comfort, not to mention the tanga or shorty. The key is to find the cut that suits your body shape, your outfit, and above all, makes you feel good.

Frequently Asked Questions

What is the average lifespan of a pair of underwear?

It all depends on its quality, how often it's worn, and how it's cared for. A well-made model (cotton-elastane blend), washed at 30°C without fabric softener, will last for one to two years without losing its shape or comfort. Conversely, a low-quality item might be ready for the bin after just a few months.

Boxer briefs, briefs, or boxers: what should a man choose?

The choice depends primarily on personal comfort and intended use.

  • Boxer Brief (or Trunk): The most versatile. It offers ideal support and good coverage, perfect for everyday wear and sports.
  • Brief: The champion of support. With its minimal fabric, it's unbeatable for discretion under fitted trousers.
  • Boxer: Loose and breathable, it's the king of at-home comfort, ideal for relaxing or for sleeping.

How do you care for period underwear?

To maintain their effectiveness, meticulous care is key. Rinse them in cold water immediately after wearing. Then, machine wash at 30°C, preferably in a laundry bag. The golden rule: never use fabric softener or bleach. Finally, always air-dry! The tumble dryer is their worst enemy, as the intense heat damages the waterproof technical layers.
