Sydney Sweeney has spoken candidly about growing up with a 32DD bra size in Washington state and says she 'never felt confident' in her body until years later, a shift that has now fed directly into her new lingerie line, SYRN, launched in January.

The Euphoria actress told US Weekly that the insecurity she felt as a teenager with larger breasts eventually pushed her to design underwear she believes actually works for women's bodies rather than against them.

For starters, Sydney has spent the past few years under an intense spotlight, becoming one of Hollywood's most in-demand young stars thanks to her role as Cassie Howard in HBO's Euphoria and a string of high‑profile film projects.

On red carpets and in magazine shoots, she is often framed as a modern bombshell, but Sydney Sweeney has repeatedly said that the confidence people now assume came easily was hard‑won, and that her on‑screen work was part of that process rather than a reflection of how she had always felt.


How Euphoria Helped Reshape Sydney Sweeney's Confidence

In her latest interview, she strips that journey right back to middle school. 'I grew up with boobs. I was wearing a 32DD in sixth grade, and I never felt confident,' she said. 'I never had anything I felt good in, and I just wanted to hide.'

Sydney has long said that playing Cassie in Euphoria shifted something. The character is frequently sexualised on screen, her body used as a plot device and a mirror for teenage gaze, and she admits that working through that storyline prodded at her own unease. 'It wasn't until [I played] Cassie in Euphoria that I started realising it's actually powerful to be confident; our bodies are incredible,' she explained. 'We should embrace [them] and feel really good in our skin.'

That sounds tidy written down, but she makes clear the path was not straightforward. On set, the reality of costume fittings bit hard. Sydney says many of the looks she wore as Cassie exposed the limits of standard lingerie design for anyone who doesn't fit a narrow template. 'I'd always be like, 'Oh, this fit doesn't work. I don't have the support I want. The straps are digging into my shoulders or it's kind of itchy and riding up,'' she stated.

Those frustrations slowly turned into a plan. While filming, Sydney Sweeney began collecting reference images and ideas for what she wished existed. 'I started a whole Pinterest board of thousands of photos of inspiration, and I [thought], 'I should actually do this.' And we put it together.' The result was SYRN, announced on Instagram and officially launched at the start of the year, with Sydney positioning herself not as a celebrity collaborator but, in her words, 'the sole founder.'


Sydney Sweeney's SYRN Lingerie Built From 'Real Life' Frustrations

SYRN currently offers bras and underwear in 44 sizes, from 30B to 42DDD, with prices under $100, which the brand equates to about £73. Products are grouped into collections called Seductress, Romantic, and Comfy, an unsubtle nod to the different versions of femininity Sweeney appears to be trying to hold at once.

Speaking to Elle, Sydney made it clear she sees a gap between how lingerie is marketed and how it performs. 'I wanted to build a lingerie brand that feels like it understands women instead of talking at them,' she said. 'Syrn is about confidence without pressure, feeling sexy, powerful, soft, playful, or all of the above, depending on the day. As the sole founder, my vision was to create something that lives in real life and doesn't hold anyone back.'


Tucked into that last line is a quiet rebuke of designs that look good in a campaign but fail under a T‑shirt or a 10‑hour shift. She is not pretending underwear will rewrite deep‑seated body issues, but she is outspoken about the cumulative effect of everyday discomfort. Sydney Sweeney underlines that no single blueprint will do. 'B--bs and bodies are like fingerprints; everyone's are different, and I wanted to design for that.'
