Izzy Oller: The Future of Fashion, Sustainability & Personal Style

Written & Interviewed By : Hannah Corbett

Fashion is a language—a way of telling the world who you are without saying a word. It’s about mixing personal taste with trends, picking and choosing what works for you, and making a statement that feels authentic. And in 2025, one of the biggest trends might just be… being yourself.  And with the help of Izzy Oller, that might be easier than we think.

You might know her from tiktok videos that read ‘not saving my “cool” outfits for a special occasions’, her engagement photos, her dachshund puppy, or her business thx, it's thrifted.  I  had the delightful chance to speak with Izzy, a fashion creator known for her effortless blend of timeless staples and modern trends, but most of all her amazing thrifting finds. She’s a firm believer in curating a wardrobe that reflects personal style rather than chasing fleeting fashion cycles. Our conversation spanned sustainability, personal style, and the rise of upcycling, offering a glimpse into the future of fashion.

The Birth of Thx, It’s Thrifted

For many, the COVID-19 pandemic was a time of uncertainty and change. But for Izzy, it was the spark that ignited a thriving business. At just 21 years old, Izzy has turned her passion for thrifting and fashion into a full-time career. But her journey to this point wasn’t a linear path. It all began during quarantine when Izzy, like so many others, was left with more time at home than she knew what to do with.

"I was finishing my junior year of high school when COVID hit, and then going into my senior year, I was thinking a lot about college and what was next," she recalls. "But I was bored, so I started selling clothes just to clear out my closet. There wasn’t really anything else to do."

Though she was new to the world of social media, Izzy found herself drawn to TikTok.  "I had never really posted on social media before. My parents were really strict about it, and I wasn’t even allowed to have an Instagram. But TikTok was taking off, so I started posting silly outfit videos. Looking back, they were super cringe, but it was fun."

As her following grew, so did her interest in thrifting. People started asking about her clothes, and Izzy thought, "Well, I’m running out of things to post, so I guess I could go thrifting!" As thrift stores began reopening, Izzy jumped at the opportunity to start curating unique pieces for herself and her growing audience.

"It just kind of took off. I had a few viral TikToks and Instagram videos, and I realized that I could turn this into something more. I wasn’t expecting it, but it all came together in such a spontaneous way," Izzy says.

Despite the excitement of her newfound success, Izzy’s parents were cautious at first. "They were like, 'You need to go to school and get a degree, that’s the thing to do.' But once I showed them that I was building a business, they became very supportive.”

As her online communities grew, she dove deeper into the world of fashion, focusing on thrifted finds, upcycling, and sustainable shopping. 

"I love when things happen spontaneously, when you don't even know that something could become anything. It’s crazy to think that this all started just because I had some extra time during quarantine," Izzy says with a laugh.

On the Shift Toward Sustainability

Izzy emphasizes that sustainability in fashion isn’t just about buying from ethical brands—it’s about how you wear and care for the clothes you already own. "People are realizing they don’t need a new outfit for every occasion," she says. "Re-wearing and styling pieces in different ways is not only practical but also a form of creative expression."

The rise of vintage shopping and thrifting plays a big role in this movement. "There’s something special about finding a one-of-a-kind piece with history," Izzy notes. "It’s more meaningful than buying fast fashion that everyone else has. There’s an emotional connection to a vintage piece that just doesn’t exist when you buy something off the rack."

Izzy also points out that brands are becoming more aware of the demand for sustainability, with many incorporating secondhand and upcycled collections into their stores. "We’re seeing more brands partner with vintage resellers or launch their own resale platforms. It’s a big shift from the ‘wear once and toss’ culture we used to see."

Personal Style Over Trends

Emma Chamberlain recently predicted that personal style will take center stage, with people focusing more on their own aesthetic rather than following every trend. Izzy agrees, stating, "The key to great style is knowing what works for you and sticking to it. If your best friend were to describe your style, what would they say? That’s what makes you stand out."

She also encourages people to have fun with fashion. "Experimenting is important, but you don’t have to buy into every micro-trend. If you love something, wear it—even if it’s ‘out of style’ by social media standards. The best-dressed people aren’t always the trendiest—they’re the ones who wear their clothes with confidence."

One of the challenges of personal style in the digital age is the pressure to keep up with what’s new. Izzy shares her own approach: "I try to focus on what I actually love, rather than what’s trending at the moment. My wardrobe is built around pieces I know I’ll wear for years, not just for a season."

Izzy also notes the growing popularity of reselling curated vintage finds. "Not everyone has the time or patience to thrift, and that’s where curated resale shops come in. I spend hours in thrift stores multiple days a week, sorting through everything and making sure the pieces are cleaned and ready to go. I do the hard part so people can just enjoy shopping."

She adds that many people love the idea of thrifting but don’t have the patience for it. "Friends would always say they wanted to thrift with me, but after 20 minutes, they’d be ready to leave. I could spend hours searching for the best pieces. It’s a skill, and I love being able to share that with others."

She emphasizes that the best finds happen unexpectedly. "The day I decide not to thrift, I end up finding the best things. One time, I went in and found five designer bags. I grabbed them and left immediately because, hello, that was meant for me!"

Vintage Fashion and Bridal Style

Izzy’s love for vintage extends beyond everyday fashion—it even influenced her wedding dress choice. "My wedding dress is vintage," she shares. "There’s a vintage bridal shop in Atlanta called Vionnette Bridal, and that’s where I found it."  Which will set the scene perfectly for her Father of the Bride backyard wedding.

She recalls initially buying a dress from a traditional boutique but quickly feeling regret. "Apparently, this is completely normal, but I just knew I had made the wrong choice. I decided to try on dresses at Viennet Bridal just for fun, and I ended up finding the most gorgeous dress. I started crying. I knew it was the one."

Despite the excitement, Izzy faced a dilemma. "My mom had gifted me the first dress, but I knew if I didn’t get this vintage dress, I’d regret it forever. So, I got a second dress, and now I have to figure out how to sell the first one."

She found inspiration in Kleinfeld’s new resale platform, Kleinfeld’s Again, which helps brides resell their wedding dresses. "It’s so smart on their part, and I think that’s what I’ll end up using. But I’m waiting for the custom veil to arrive first."

Beyond her wedding dress, Izzy has been curating a wardrobe of vintage pieces for her bridal events. "Almost everything I’ve gotten is vintage, except for my shoes. Those are new because I need them to be comfortable and reliable."

The future of Thx, It’s Thrifted

Izzy Oller’s journey from a bored high school student during quarantine to a successful full-time fashion creator is a testament to the power of spontaneity, passion, and embracing the unexpected. What started as a simple way to clear out her closet turned into a thriving business fueled by her love for thrifting, sustainable fashion, and building a community. Today, at just 21 years old, Izzy is carving out her own path in the fashion industry, focusing on resale, upcycling, and inspiring others to embrace their personal style. And as for the future of thx, it’s thrifted? You’ll just have to wait and see.  But I know, no matter what Izzy does, it’s going to be rich.
