Kate Spade Customer's Heartfelt Letter About Fashion Designer Goes Viral

Kate Spade's death by suicide left a mark on family and friends, as well as on longtime customers and fans of the fashion icon and her namesake brand.

One woman from Canada was so affected by the designer's sudden passing that she decided to write an open letter to Spade on Facebook, telling a heartwarming experience she had with her daughter at one of Spade's stores.

The letter, which has gone viral according to The New York Post, has been shared by thousands of social media users.

"Dear Kate Spade," Heather Delaney wrote. "Almost four years ago, during a family vacation to Florida, I decided it was time to take my daughter, Elle (who was two months shy of six years old at the time), for her very first Kate Spade experience."

Delaney admitted she "couldn't sleep: the night before because she was so excited.

"My husband would laugh as we laid there in the bed, me jumping with excitement, in anticipation of her and I getting matching bags the next morning," Delaney wrote. "This was a serious mama dream come true."

Delaney's daughter would get "the crossbody" and she would get the full size handbag.

"Brilliant," the mom recalled telling herself. "Let's do this, Elle."

But when the pair got to the Kate Spade store, plans apparently changed.

"We walk in. I show her the white [bags]. The black ones. The legendary stripped ones. Nope. Nope. Nope," Delaney continued, highlighting how none of the bags appealed to her daughter's "style."

"Then, she saw it. The first Kate Spade item that she would call hers."

A pair of black, furry earmuffs.

The proud mom went on to say that she wished Spade could've been there to see her daughter that day and felt the love she helped provide for them.

"Kate, I'm sorry that we could not bottle that up for you," wrote Delaney. "I'm sorry that we could not bottle up every grin, every laughter, every happy heart that walked through your stores. I'm sorry that we could not gather every smile that you put on a humans face, whether it was because they just found the most loveliest brooch for their wedding day, the most exquisite pair of earrings to wear on their graduation day, or even the most coziest pair of earmuffs to wear around Florida…and lay those smiles in your lap."

Delaney then talked about Spade's mental health issues and described her guilt after her icon's death.

"I'm sorry that some are still scared by mental health, Kate. I'm sorry that some don't understand it," Delaney said. "I'm just so sorry you were sad, while you made so many others happy. So incredibly happy... I'm sorry, Kate, that we could not gift you the happiness that was felt in this six-year-old's body that day... I kinda feel guilty now for feeling so much happiness that day, wondering now if you were perhaps sad that day."

Delaney finished the letter by praising Spade for being a "powerhouse" businesswoman, wife and mother — and provided an update on the earmuffs.

"You lived a life that others could only dream of," Delaney said. "I hope that you are now at peace... and happy. I hope you are so, so incredibly happy..."

"Oh, and if you're wondering, Kate, no, I passed on the matching earmuffs. But I did get the most loveliest black purse to match the black in her earmuffs. Bless it."
