Plus-size seamless underwear: what really changes in the design

Offering underwear in plus sizes, up to 3XL, is not just about enlarging an existing pattern. Designing a panty that offers the same comfort, support, and invisibility under clothing on a more generous silhouette requires a different design approach.

Here's what distinguishes a truly well-designed seamless panty for plus sizes.

Why the design must be rethought, not just enlarged

A size S panty and a size 3XL panty cannot simply be proportional to each other. Pressure points, how the fabric conforms to curves, the distribution of elasticity, and the required support vary significantly depending on body shape.

A panty mechanically enlarged without design adjustments can slip, roll up, compress in the wrong places, or lose its invisibility under clothing. Key areas to rethink include the height and width of the waistband, the cut of the crotch, the distribution of elasticity over the hips, and the length of the gusset.

At LICA Wear, plus-size patterns have been developed considering these parameters, to ensure that each panty offers the same second-skin comfort regardless of the size worn.

The high-waisted thong in plus sizes

The high-waisted seamless thong is particularly suitable for women who wear fitted clothing or who want gentle support on the lower abdomen.

Its higher waistband creates a flattering line and remains discreet under fitted pants or a bodycon dress, even in plus sizes. The elasticity integrated directly into the fabric, and not in an attached elastic band, ensures support without compression and without marks at the end of the day.

This is often the preferred style for women who wear formal or fitted clothing, as it subtly smooths the silhouette without creating a feeling of constraint.

The seamless bikini brief in plus sizes

The seamless bikini brief is the most versatile cut for everyday wear. It offers moderate coverage with a classic cut on the hips, suitable for all activities.

For active women who move a lot, play sports, or spend long hours on their feet, the seamless bikini brief offers the necessary freedom of movement without chafing seams or digging edges.

The material: even more important in plus sizes

The fabric plays a central role in the comfort of a plus-size panty. A fabric that is too rigid compresses. A fabric that is too loose slips. The balance lies in a sufficiently high percentage of elastane to offer 360-degree elasticity, combined with a soft and durable nylon.

LICA Wear's seamless panties are made of 63% nylon and 37% elastane. This percentage of elastane, significantly higher than the market average which is generally around 20%, ensures that the fabric naturally adapts to curves without creating tension or compression, regardless of the size.

The 100% pre-shrunk cotton gusset ensures optimal breathability in the crotch, a detail particularly important for comfort on long, active days. To learn more about the role of the gusset, consult our complete guide to the cotton gusset.

How to choose your size

In plus sizes as in standard sizes, the most reliable reference is your numerical pant size, which is the DENIM or US column in our size chart.

If you are between two sizes, opt for the smaller one: the stretchy fabric adapts, and a slightly snug panty will stay in place all day. A panty that is too large slips and loses its second-skin effect, regardless of the size.

Invisibility under clothing: the same requirement in all sizes

Invisibility under clothing is a legitimate expectation regardless of the size worn. The laser-cut edges of LICA Wear seamless panties create an ultra-flat finish that leaves no trace under leggings, bodycon dresses, or fitted pants, in size S as in 3XL.

According to a study published in the Journal of Fashion Marketing and Management, size inclusivity in underwear has become a fundamental expectation of consumers, directly linked to their sense of well-being and self-confidence in everyday life.
