21 best seamless underwear to solve any outfit dilemma
A VPL is an unfortunate faux pas, but its something that happens to literally everyone unless you invest in the best seamless underwear.
Ever slipped into a brand new, form-fitting summer dress only to realise your panty line is on display for all to see? Not in a pair of no-show undies you won't. When you don't feel like going commando – especially if said frock is above the knee – they're your best bet.
Not praised nearly enough, seamless underwear is an absolute must for your top drawer and – good news incoming – there are full-coverage options as well as G-strings and thongs on the market these days. Some of the best bras come in the seamless variety, too, so you can rest assured that your outfit will be smooth from top-to-toe.

While cotton underwear usually takes the crown as the most comfortable base layer you can own, you'd be surprised at just how ‘invisible’ a lot of seam-free designs are (read: via feel as well as appearance). The last thing you want is a waistband that ends up rolling down and digging in anyway. We recommend looking to the best shapewear brands for styles that'll stay put and keep everything looking smooth.
SKIMS has some of the best seamless underwear we’ve ever encountered – we might even favour them over the signature bodysuits. As well as the seamless sculpting mid waist briefs, which provide core support and lift your bum while smoothing out any harsh lines, the label also features seamless bras. The Seamless Sculpt Bra and the Soft Smoothing Bralette are just two of our favourites, and sit flawlessly (unsurprisingly) beneath anything bodycon.
Are seamless underwear better?
In short: yes. If you're looking for a completely polished surface and unwrinkled outfit, invisible bras/stick-on bras, strapless bras and seamless knickers are exactly the sort of thing you should opt for. Not only do seamless pants create a smoother appearance, but they're also gentler on your skin. Think about it: how often do harsh seams and tight waistbands irritate you? If the answer is often, you know the solution. Seamless styles feel like a second skin.
Whether it’s a particularly tight wedding guest dress, skort, slip, loungewear or pair of gym leggings you’re planning to wear, don’t let your undies ruin it. You needn’t spend a fortune on ensuring your outfit is fail-safe, either, the high-street has some top-performing options for you to shop alongside or instead of the designer lingerie brands.
