Product Insights
The Wacoal B-Smooth High-Waist Classic Brief, priced at 22 CAD and in stock, is the brand's best-selling panty collection, engineered to create a smooth, line-free silhouette under fitted clothes with a matte finish that prevents visible sheen. Its stretch-recovery nylon/elastane material offers 40% more stretch recovery than standard microfiber to prevent bagging, while the 93% nylon content resists abrasion against thin spots. A cotton gusset wicks moisture, reduces chafing, and maintains pH balance. All 539 Zappos reviewers rate it true to size. However, to preserve its stretch recovery, abrasion resistance, shape, and matte finish, the brief requires hand-washing and drip-drying.

Everyday comfort wear
Wacoal designed its B-Smooth panties for around-the-clock comfort, using ultra-soft, smooth fabric. This high-waist brief sits at the waist with a high cut leg opening, which one reviewer found comfortable and easy to move in. A fit to consider if you like a brief that actually reaches your waist rather than sitting below it.[1,4]
For a smooth look under clothing
When you want underwear that won't show under outfits, this high-waist brief is designed to sit at the waist with a wide elasticized waistband above the hips. One reviewer reported that because the brief comes up very high on them, everything looks smooth on the torso. The B-Smooth fabric has a matte finish that disappears under clothing and lies flat against the skin.[1,2,3,5]
Everyday brief with full rear coverage
A seamless high-waist brief designed for days when you want full rear coverage under your clothes. The wide elasticized waistband sits above the hips, and the smooth knit construction keeps the look streamlined. A gently contoured seat seam is visible as a faint vertical stitch line.[5]
A simple starting point for trying the fit system
This high-waist brief is a straightforward piece to try before moving on to more complex pieces in the fit system. The source author suggests starting with the B-Smooth brief, or the Visual Effects Minimizer, to test the fit system before investing in a body briefer.[2]
Product comparison
Compared within this brand.
| B-Smooth High-Waist Classic Brief: Choose this if you want a seamless, high-waist brief with full front and rear coverage and high-cut leg openings, supported by a wide elasticized waistband that sits above the navel and hips. Its smooth nylon-elastane microfibre body (93% nylon, 7% elastane) with a cotton-blend gusset has a matte finish that one source says disappears under clothing, and it is designed for all-day comfort. Sizes run small to large in Steel Blue; one reviewer sized down for a snugger, hold-you-in fit, and sizing may differ from other regions, so check your fit preference.[1,2,5,6,7] | Understated High-Waist Classic Hipster Supima® Cotton: Choose this if you want a high-waist classic hipster with full rear coverage in a soft, stretchy blend of 84% SUPIMA cotton and 16% spandex, described as very comfortable. Its ultra-thin elastic waistband and leg elastic are designed to lie flat against the body, and the smooth matte knit shows no visible center front seam. Note that hand washing is strongly recommended and machine drying is excluded, and this listing offers the brief in size small.[8,9,10,11,12] | Lace And Embroidered Flowers Classic Brief Nylon: Choose this if you want a high-cut brief that sits high on the hip, made from sheer stretch nylon-blend lace with embroidered floral detailing and a thin elastic waistband. It suits shoppers who prefer a fully cotton gusset and full seat coverage in a classic silhouette, in Black or Lilacs across sizes Small to X-Large, with a matching bra sold separately. Note that the sheer nylon fabric is semi-transparent, which may matter if you prefer more opaque underwear.[13,14,15] |
