BESTENA Slip Shorts Review: Do They Actually Work Under Dresses?

Quick Verdict

After two weeks of wearing BESTENA slip shorts under everything from bodycon midi dresses to loose linen pants, I'm ready to give you an honest take. The short version: they're one of the more reliable budget options for eliminating visible panty lines and preventing thigh chafing, but the waistband tightness after extended wear is a real caveat. I'd give them a 4.2 out of 5 — they're worth buying if you need an affordable everyday solution, but size carefully and don't expect athletic-grade performance.

What Is the BESTENA Slip Shorts?

The BESTENA slip shorts are seamless, mid-length undergarment shorts designed primarily for women who want a smooth line-free silhouette under dresses, fitted pants, and skirts. Made from a blend of 90% polyamide and 10% elastane, they sit somewhere between traditional underwear and light compression shorts. The brand markets them as shapewear, but don't expect major tummy control — these are more about surface smoothing and thigh coverage than figure sculpting.

They come in a nude-friendly color range (the "Nude" option is technically a light beige rather than true skin-tone inclusive) and are constructed with a seamless knit that eliminates traditional sewn edges. The mid-length cut runs from waistband to approximately mid-thigh, offering more coverage than boyshort underwear but less than traditional bike shorts.

Key Features

• 90% polyamide, 10% elastane blend for a skin-friendly, stretchy feel
• Seamless construction eliminates visible panty lines under fitted clothing
• Mid-length design provides full thigh coverage and prevents chafing
• Full-rise waistband sits at natural waist for secure positioning
• Lightweight fabric — approximately 40% thinner than standard cotton underwear
• Multi-purpose: daily wear, workouts, layering under dresses and skirts
• Machine washable on gentle cycle without losing elasticity quickly

Hands-On Review

I pulled these on the morning of a particularly humid Tuesday, pairing them with a fitted midi dress for a full workday. First impression: the fabric feels immediately cool against skin — not cold, but noticeably less heavy than the cotton underwear I usually wear. The seamless edges disappeared completely under the dress's thin jersey material. By hour four, I forgot I was wearing them. That continued until approximately hour six, when the waistband started registering as a subtle tight pressure across my lower abdomen.

What surprised me was how well they performed under pencil skirts — an outfit I typically dread in warm weather because of thigh-on-thigh contact. The mid-length coverage genuinely reduced friction. I walked to and from lunch (about 20 minutes total in 82°F heat) without the painful chafing I usually experience in that scenario. By the end of the day, I had zero redness on my inner thighs, which almost never happens for me.

Week two, I tested them as actual bike shorts for a 45-minute indoor cycling class. Here's where expectations needed adjustment. The polyamide-elastane blend doesn't wick moisture the way dedicated athletic shorts do. I wasn't dripping, but I definitely noticed dampness that lingered longer than I'd like. For yoga and Pilates, though, they performed fine — no riding up, no rolling at the thigh, good range of motion.

After a dozen home laundry cycles (cold water, gentle, air-dried), the elastic hasn't degraded noticeably. The fabric has softened slightly, which I actually prefer. One thing nobody mentions in the listings: the nude colorway photographs differently under warm versus cool lighting, so what looks seamless in your bedroom mirror might catch slightly under fluorescent office lights.

Who Should Buy It?

• Office workers who wear fitted dresses or pencil skirts — the seamless construction is genuinely invisible under professional attire, even with thinner fabrics.
• Women prone to thigh chafing in warm weather — the mid-length coverage creates an effective barrier without the bulk of bike shorts.
• Anyone who wants smoothing under bodycon or tight-fitting pants — the light compression-like fabric smooths without uncomfortable squeezing.
• Budget-conscious shoppers who need everyday versatility — these aren't specialized athletic gear, but they're competent across multiple use cases.

Skip these if you need significant tummy control or body shaping (these are smoothing shorts, not shapewear), if you're shopping for intense athletic performance in high-sweat environments, or if you're sensitive around the waistband — the compression there can feel restrictive after several hours of sitting.

Alternatives Worth Considering

If BESTENA's waistband tightness is a dealbreaker for you, the Effergirl Seamless Shorts offer a similar polyamide blend but with a wider, softer waistband that stays comfortable longer. They're marginally more expensive but handle extended wear better.

For a more athletic-focused option, the Athleta Putty Shorts are designed with genuine moisture-wicking fabric and stay completely in place during cardio — though at nearly three times the price, they're overkill if you primarily need them for daily undergarment use.

The SVOKIO 2-Pack Slip Shorts provides identical functionality at a comparable price point, with the added value of getting two pairs. They're worth considering if you want backup pairs or different color options without committing to a single style.

FAQ

Final Verdict

BESTENA slip shorts deliver exactly what they promise: a seamless, lightweight, mid-length undergarment that smooths your silhouette and prevents thigh chafing without breaking the bank. They're not perfect — the waistband pressure after hours of wear is a legitimate drawback, and athletic performance is limited — but for everyday office and casual wear, they outperform many pricier alternatives I've tested. If you're between sizes, size up without hesitation. The fabric quality and construction hold up well past the first few washes, which is more than I can say for several competitors in this price range.
