A bride wore a sheer, sparkly dress with a dramatic slit to her intimate destination wedding in Tulum

California-based couple Thainá, 28, and Charn, 35, were introduced through a mutual friend in 2016.

Thainá is the founder of the cannabis wellness company Nowdays, and Charn also works in the cannabis industry.

At first, Thainá planned for their relationship to be platonic, but she and Charn quickly developed a romantic connection. They've been together ever since.

The Baks got engaged at the end of 2018.

They planned to get married in Tulum, Mexico, in January of 2020, but they had to postpone because of the coronavirus, as their 150 guests would be traveling from all around the world.

They set their new wedding for January of 2021, and they scaled their guest list down to just 20 people.

"They're unique," she said of why she was drawn to Berta's gowns. "You can get a boho vibe from them, but you're not going to look beachy."

Thainá's mom traveled to California from their home in Brazil about four months after Thainá got engaged to help her find a dress.

She set her budget at $17,000.

The form-fitting dress had a cutout on the bodice, keyhole back, and frames of see-through lace.

It was pretty, but the dress didn't feel right to Thainá.

"I think it didn't represent who I am as a person," she said of the gown, which was a bit more traditional than she had been imagining.

"I feel like I'm more of a free spirit, so I wanted something that could represent my personality," she said.

"The Bella was the only option," Thainá told Insider of the Muse by Berta dress, which she had seen online months before she started wedding dress shopping.

The dress had a form-fitting, sheer bodice with a full tulle skirt.

The flowing skirt had a thigh-high slit on the left side, which Thainá liked immediately.

The tulle skirt was also sheer, giving the bottom of the dress a sultry look.

The sheer, glittery bodice had a low-cut neckline, which was covered in a layer of sheer fabric for comfort.

The straps were embroidered with delicate flowers, and the bottom of the bodice connected to the skirt with more floral detailing.

"I felt like it looked like a fairy tale," Thainá said.

"You can be sexy and romantic in that dress," she told Insider.

The dress cost $6,000, which was way under Thainá's budget.

She got her alterations on the dress done in Brazil, where her family is from, so they cost just $200.

She got the train shortened and had the dress brought in a bit.

Thainá told Insider that she considered wearing shoes with a fuller heel since the wedding was on the beach, but she ultimately opted for stilettos because she is on the shorter side.

The white heels had straps that went up her ankles, embodying the sultry and romantic vibe of her dress.

Thainá wanted a simple hair and makeup look, as she wanted to feel like herself on her wedding day.

She had a trial with a makeup artist, but after the experience, she felt like she could create the look she wanted by herself.

Prep Hair Tulum did her hair.

"I wanted it to last forever," Thainá said of her wedding day, as she didn't want to take her dress off.

She got compliments on her gown from both the guests at her wedding and passersby on the beach around them.

"It was magical," she added.

The pink suit matched the tropical vibe of the wedding.

Charn had it custom-tailored at an old-fashioned tailor in California. It was ready just two days before he and Thainá left for their wedding.

The inside of his jacket was also embroidered with his name.

Thainá told Insider that Charn got "emotional" when he saw her in her wedding dress.

He was also surprised by the gown, as he had imagined her in a mermaid-style dress.

But he thought she looked beautiful.

Chris and Ruth Photography captured the moment, as well as the rest of the couple's wedding day.

Because they only invited 20 people, the Baks decided to make their wedding a week-long celebration rather than just one day.

The nuptials took place at Casa Malca Tulum, and guests stayed at the Aldea Canzul.

The couple combined the beach venue with a boho vibe using dried flowers and rugs.

Pure Love Floral Design provided the couple's intricate archway, while Archive Rentals provided the decor.

Daniela Parra designed the event. Luca Zannelli provided audio services.

Her dad walked her down the aisle at the beach.

"I've never felt that way before," Thainá told Insider.

Even though Charn and Thainá saw each other before the actual ceremony, finally being married felt different to them, as Thainá told Insider.

Thainá didn't want to feel encumbered in her intricate gown during her reception, so she changed into a slip dress she bought online.

The dress was only $200, and Thainá loved the way it looked.

"I can use that dress any time," she said of the gown, telling Insider that she plans to rewear it for occasions in the future.

Thainá went to three stores before she found her dress, and she found that consultants were hesitant to let her try on too many dresses.

Many brides get confused if they see themselves in a lot of gowns, but Thainá said she wished salespeople would have let her enjoy the process of looking for a wedding dress more.

"It's a special time for brides," she said.

Thainá advises that brides look at dresses online and bring screenshots or physical photos of gowns they like to stores when they shop for their wedding dresses.

She thinks it makes the actual process of shopping run more smoothly.

"We help each other with everything," she said. "We're best friends, and I've never had that kind of relationship before."

"It feels so easy," she added.

"There's no judgment," she added.
