Spanx Bra-llelujah! Unlined Bralette Review: Is this the world's comfiest bra?

The Spanx Bra-llelujah! Unlined Bralette combines Spanx's years of expertise creating comfortable yet hardworking shapewear to create one of the best bras on the market. If you are looking for a bra that feels like, well, you’re not wearing one, this might be the bralette for you. 

We’ve put it through its paces with real-life testing to give you the confidence you need to take the plunge (pun completely intended). Spoiler alert: we loved it and think it’s a worthwhile investment, assuming you don't have large boobs.

It has impressive stretch, secure fit and enough support from the wide and comfortable straps for anyone with small or average-sized boobs.

First impressions 

The beauty of this bra is in its simplicity, so there’s limited ‘wow’ factor when you unpackage it. 

What struck me first was how teeny-tiny it looked and, as there’s no back clasp, I was initially nervous that it might not fit over my head and shoulders without snapping. 

But as soon as I started to put it on, my fears of getting stuck (or having to quickly become a master contortionist) melted away. The fabric is seriously impressive – think the stretch of a pair of tights with the softness of your favourite bedtime T-shirt.

As you’d expect from a Lycra mix, it snapped straight back into shape as I wiggled it into place. The fit is firm and secure, but miles away from being uncomfortably tight.

How comfortable is the Spanx Bra-llelujah! Unlined Bralette?

It’s official: we’ve found the world's most comfortable bra – and it comes as no surprise that this bralette is one of Spanx’s bestselling styles in the US. 

This is a bra you could comfortably wear all day long and not be desperately rushing to take off the minute you get through the door. The Spanx Smart Straps self-adjust, for soft, niggle-free support ‑ and no tell-tale shoulder dents come evening. 

How supportive is the Spanx Bra-llelujah! Unlined Bralette?

In recent years, lingerie trends have led us away from more traditional bras (full cup, padded and underwired) and instead towards soft-cup styles that offer a more natural silhouette.

Comfort is, of course, the biggest selling point here, but the Spanx Bra-llelujah! Unlined Bralette won’t provide enough support for everyone. 

The lack of wiring means it’s only really suited to smaller busts that don’t need a huge amount of lift, and wouldn’t offer bigger boobs the security and hold they need for everyday wear.

Having said that, if you have a bigger bust and are looking for a cosy sleep bra, or extra night-time support around the time of your period, then this is a great choice.  

What is the shape and appearance like?

The Spanx Bra-llelujah! Unlined Bralette’s key features are the plunging triangle shape, supportive shoulder straps and wide, clasp-free back. What’s missing is important, too, and this bralette is free from padding, underwiring and strap adjusters. 

The result is a sleek silhouette, a gently lifted bust and a bra that’s easily concealed under clothes. The shade range is limited at the moment, with just a pale pink, nude and black on offer, but I’ve been told new shades and seasonal colourways are in the pipeline. 

What are its unique features?

I came for the barely there shape, but in the end it was Spanx’s patented all-hosiery back that won me over as one of the best bras for 'back fat'. Following spinal surgery, I have a disproportionate amount of scar tissue on one side, something that becomes more obvious when I wear a bra. In the Spanx Bra-llelujah! Unlined Bralette, it’s barely noticeable, as the stretchy fabric skims straight across. Anyone conscious about the look of bulging around the band is likely to have a similar experience.

Washing instructions

The lack of wiring might tempt you towards popping this bralette in with a normal load, but to keep the elastane firm, stick to a cold hand wash only.

It’s not suitable for tumble drying, so lie flat or hang on a drying rack to dry. 

Is the Spanx Bra-llelujah! Unlined Bralette good value for money?

Thanks to the seamless shape, this bra is uniquely placed to work under pretty much any outfit. With plenty of potential to max out on your cost per wear, you’ll quickly feel you’ve got your money’s worth. 

Is the Spanx Bra-llelujah! Unlined Bralette true to size?

Using clothes sizing over cup and back bra sizing, it’s not immediately clear which size to go for. Thankfully, the handy size convertor on the Spanx website is nice and easy to navigate, and even flags the two options to consider if you find yourself between sizes. 

If you fall into the L-XL category (size 34D and upwards), the bra has an extra layer of fabric built into the cups for additional support. 

What else is in the Spanx range? 

The brand that spurned a thousand copies, Spanx was first dreamt up by founder Sara Blakely as she struggled to find smooth, seam-free briefs to wear under a figure-hugging white dress. She chopped the feet off her control-top tights before heading out the door – and the rest, as they say, is history. 

The brand is uniquely dedicated to solving our niggling wardrobe dilemmas, from Spanx leggings to knickers, tights to shapewear. They even have a compression range designed especially for men.
