Smart&Sexy vs Tani is a useful comparison because the two brands answer two very different questions. Both appear in our best lingerie brands roundup, but where one is about flirty, affordable lace and lift, the other is about quiet, sustainable, second-skin comfort. If you're deciding where to spend, this head-to-head breaks down fabrics, fit philosophy and who each brand truly suits.
The quick answer
Choose Smart&Sexy if you want affordable lace bras, push-ups and matching sets with real lift. Choose Tani if you want sustainable, ultra-soft TENCEL™ Modal basics that feel like a second skin.
Smart&Sexy: affordable, flirty, lift-focused
Smart&Sexy is a woman-owned brand with a clear motto: affordable doesn't have to mean cheap. Its catalogue centres on lace and mesh bras — the Signature Lace Push-Up (over five million sold), the Add 2 Cup Sizes Push-Up with double-bump molded padding, and the Retro Lace & Mesh Unlined Underwire that runs to a G cup.
Coverage spans full-figure plus sizes up to 46G, and most bras pair with matching signature-lace or mesh panties for a complete set. The aesthetic is pin-up-inspired and intentionally sexy, at prices that make multipacks easy.

Tani: sustainable, soft, second-skin comfort
Tani takes the opposite philosophy: comfort you forget you're wearing. Its Silktouch range is built from 94% TENCEL™ Micro Modal Air with 6% elastane — a beech-wood-derived fibre finer than silk at 0.8 dtex — across wire-free soft bras, flat-seam panties and boyshorts.
The focus is on breathability, moisture-wicking and a barely-there feel rather than lift or lace. The brand also leans sustainable, citing responsibly sourced materials produced with less energy and water. Bras have adjustable straps and removable padding for a personalised, gentle fit.

Head to head
Fabric
Smart&Sexy leans on nylon, lace and mesh blends engineered for shape and lift. Tani is all about TENCEL™ Micro Modal Air — sustainable, breathable and silky. If softness is your top priority, Tani wins; if you want structure, Smart&Sexy delivers.
Support
Smart&Sexy offers underwire, push-up and full-figure support up to 46G. Tani's soft bras are wire-free with light, gentle support. Bigger busts that need lift will favour Smart&Sexy; those who hate underwire will love Tani.
Style vs comfort
Smart&Sexy is flirty and occasion-ready. Tani is minimalist and everyday. Many shoppers end up owning both — a Smart&Sexy set for nights out, Tani basics for everything else.
Range and signature pieces
Smart&Sexy's catalogue is broad and bra-led: alongside the Signature Lace Push-Up and the Add 2 Cup Sizes Push-Up, you'll find the Sheer Mesh Demi Underwire for a clean, modern look, the Everyday Invisible Full Coverage T-Shirt Bra for no-show wear under anything, and matching lace and mesh panties so you can build a coordinated set. The brand even extends into bra-sized swimwear like the Long Lined Underwire Bikini Top, which carries the same lift and support into the pool.
Tani's range is quieter but surprisingly versatile. Beyond the Silktouch soft bras, panties and boyshorts, it makes a breathable 3-Pack Sportmesh Panty blending TENCEL™ Micro Modal Air with Coolmax® for hot, active days, plus loungewear, pyjamas and skirts in the same silk-soft fabric. If you want your underwear, sleepwear and travel basics to share one consistent feel, Tani delivers that head to toe.
Care and longevity
Both brands reward gentle care. Lace and mesh pieces from Smart&Sexy last longest washed on a delicate cycle in a mesh bag, air-dried to protect the elastic and lace trim. Tani's TENCEL™ Modal is naturally durable and resists odour, but like all fine fibres it prefers cool washing and low heat. Treated well, either brand will hold its shape far longer than fast-fashion alternatives.
Sizing and fit
Smart&Sexy is fit-tested and true to size, with full-figure coverage up to a 46G band-and-cup range — genuinely useful for those underserved by mainstream lines. Tani's soft bras run on adjustable straps with removable padding, so the fit is more forgiving and self-adjusting; its panties use a minimalist low-rise cut with flat seams that suit most body types. If you're between sizes or need precise cup support, Smart&Sexy's structured fit is easier to dial in.
Frequently asked questions
Is Tani worth the extra cost over cotton basics?
If softness, breathability and a sustainable fibre matter to you, yes — TENCEL™ Micro Modal Air feels noticeably finer than standard cotton and wicks moisture well. For pure budget shopping, Smart&Sexy multipacks stretch further.
Which is better for everyday no-show wear?
Tani's flat-seam, low-rise panties are built to disappear under clothing, while Smart&Sexy's Everyday Invisible T-Shirt Bra is the no-show pick on the bra side. Combine the two for a fully seamless look.
The verdict
Neither brand loses; they simply serve different needs. For affordable lace, push-ups and matching sets with real lift, Smart&Sexy is the smarter buy. For sustainable, wire-free, second-skin softness, Tani wins.
