YADIFEN Seamless Slip Shorts

For anyone who wants a layer under dresses or skirts to reduce thigh friction and add coverage, these YADIFEN slip shorts are designed as seamless boyshorts with light compression. The fabric blend is 90% polyamide and 10% elastane, and the listed set includes coffee, brown, and gray pairs. They’re also described as suitable for lounging or sleep, though their close-fitting, smoothing design is more specific than a basic pair of loose sleep shorts.

Technical details

The shorts are made from a soft, smooth-feeling fabric with a comfortable waistband and leg openings. They cover the hips and thighs, and the listing says the material is not see-through and is intended to stay in place during movement. Those are product claims, not a guarantee of the same fit on every body, the length and compression may feel different depending on your proportions and chosen size.

The set contains three colors: coffee, brown, and gray. Sizes are listed from S through 5XL, including plus sizes, and the shorts have a cotton crotch. Care instructions specify warm-water washing, non-chlorine bleach only, normal-temperature tumble drying, and no ironing.

Getting the most from it

Since no garment measurements are provided here, choosing a size without that measurement means relying on the size options rather than a direct comparison with your own measurements. Check any available size chart before ordering, especially if you’re between sizes or prefer less compression. Light shaping can smooth the look under a dress, but these are not described as firm-control shapewear.

A practical use is wearing them beneath a skirt on a warm day: they add a layer over the thighs while keeping the outfit’s silhouette relatively smooth. They can also work as simple lounge shorts at home. For cycling or workouts, the listing mentions those uses, but it doesn’t provide details about performance features such as padding or moisture-wicking construction.

Usage tips

Try them under a dress or skirt when you want more thigh coverage and a barrier between your legs. The boyshort cut also makes them an option under longer tops or jeans, though fit under close-fitting clothing will depend on how the waistband and leg openings sit on you. If the fabric bunches or feels restrictive, a different size or a less compressive style may be more comfortable.

Follow the stated wash directions to care for the blend: warm water, non-chlorine bleach only, and normal-temperature tumble drying. Avoid ironing. The listing describes the shorts as staying put, but checking their position during your first wear can help you see how they behave with your outfit and movement.

Practical doubts

Are these mainly underwear or shorts? They’re presented as underwear for dresses and skirts, with additional suggested uses as lounge or sleep shorts. The listing also mentions workout and cycling wear, but doesn’t give sport-specific construction details.

Do they come as a three-piece set? Yes. The described set includes coffee, brown, and gray colors.

What is the fabric made of? The listed blend is 90% polyamide and 10% elastane, with a cotton crotch.

When it makes sense

A solid pick if your main goal is adding a smooth, close-fitting layer under dresses and skirts, with several colors in one set and sizes extending through 5XL. You may want to skip it if you need firm compression, detailed performance features for exercise, or a guaranteed fit based on garment measurements. Compared with choosing a single-purpose shaping piece, these shorts are pitched as a more flexible everyday layer, their value depends on whether that under-dress use is what you actually need.
