Tinx is in her rich mother’s athleisure fashion era

“Rich moms love monochrome moments, like linen pants and a nice linen blouse. They love a swimsuit with a sarong over it and some amazing statement jewelry. And then they love a maxi dress because when you're on the yacht you just need something light and flowy."

If you've spent time on TikTok, you would immediately recognize this as the gospel of Tinx. I'm on the phone with the TikTok star (real name Christina Najjar) and we're chatting up summer trends, which has me wondering what fashions we can expect from Rich Moms - the subject of Tinx's many videos They Deserve 1, 5 million followers on the social media app - this season.

While Tinx is better known for poking fun at the wealthy archetypes, dishing out dating advice, and offering recommendations for the best salads in New York (where she lived) and Los Angeles (where she moved nearly three years ago), is she's become an unofficial fashion influencer — with followers asking as much about the brands she wears as they do about the "box theory." That's because of how seamlessly she goes from wearing emerging designer looks, to a brand event, to a Nirvana t-shirt, to making videos from her bed, to a The North Face x Gucci collab puffer fish, to cruising around New York City to stroll can pass.

It's this penchant for high-low clothing that likely earned her a starring role in H&M's new Hôtel Hennes campaign, in which she plays a hotel receptionist who offers dating, summer plans and fashion advice alongside celebrities like Gigi Hadid and Precious Lee. As I move on to asking Tinx about her personal style, she sheds the rich mom role and becomes the relatable creator who's earned nicknames like "TikTok's big sister" and "advice columnist, but on Instagram."

"I've worn H&M for as long as I can remember," she says. "I grew up in London and I remember when it came in. I was just so excited and I would drag my mom over there and let her buy me clothes from there.”

Ahead, Tinx on her ever-changing fashion aesthetic, the one Y2K trend she'll never bring back into her closet, and why you should wear black when you know you're going to meet your ex.

This campaign seems to be very suitable for you. What attracts you to the high-low style?
I have to give credit to my upbringing in London. High-low dressing was born on the high street, that's where it really started. I love mixing high street designers with high end pieces. I love getting things second hand. I like having a big mix of things. And H&M has always been such a big part of my wardrobe. I still really can't believe it - it's really cool to go from wearing the clothes to a campaign.

How would you describe your personal aesthetic?
It is constantly evolving. I like to dress for my surroundings. So when I'm in LA, I'm more casual. When I'm in New York, I'm a little fancier. I find that fun. Clothing is a way for me to express my feelings, so it's not always that consistent, because a lot of my fashion is based on how I'm feeling: am I in a playful mood? Am I in a sexy mood? I really only use clothes as an outward expression of what's going on with me.

Would you then say that your aesthetic has changed over the years?
Oh god yes. I mean, I went through a phase where I literally told my mom my aesthetic was "Victorian pirate." I went through many different phases. I went through a phase where I was preppy, I went through a phase where I lost a little bit of emo. I went through a period of dressing like a 60-year-old grandmother on the coast. I like going through phases. I think fashion is fun and playful and I like having different eras. So right now I'm definitely in my "rich mom athleisure" era where I just wear a lot of coordinated training sets.

How did you develop your personal style and start enjoying fashion?
I wore one [school] Wore uniform until I was 18 and I think that really developed my personal style. It made me appreciate fashion so much, the little ways girls would kind of make their outfits stand out. Some girls wore crazy socks or did crazy things with their hair and I was like, 'Wow, that's such a form of self-expression and it's something that everyone can do and everyone does their own. And there is a way to be unique [even when wearing the same uniform]."

I remember ripping off the boring button on the skirt of my uniform and sewing on this really ornate gold button I found at my house. The button wasn't even visible, but it was right under my sweater and I knew it was there.

I think that's why I've always loved personal style so much. It's just a way of expressing yourself on a daily basis.

Speaking of fashion from the younger days. Y2K fashion made a comeback this year. What are some of your favorite '00s trends that are bringing you back?
I love the color palette so the pink and purple tones, the baby blue - these are all my favourites Colours! - it was great fun. I love the makeup - the frosted eye shadow and the lip gloss. Love the hair - the space buns. I love the little matching set, I would say this is my number one trend to come back to. Whether it's a little mini skirt and crop tank or like mesh pants and a top.

Any trends you'll never wear again?
Low-rise jeans without a doubt. For me personally, these will never come back. I just can't deal with them. We never need to see them again. They are so creepy and bad.

What is your favorite fashion rule to break?
To wear pink and red together. I think it's the best color combination. The colors make me so happy and they remind me of love.

What are some of your favorite ways to shop?
I find so many cool brands from TikTok. I see all these amazing people there and it's just really cool. I love just exploring there, it's really fun. I also buy a lot second hand.

Quick question and answer session. You are a receptionist at the Hôtel Hennes. People call you to ask what to wear...

… live out your hottest summer plans?
The most important thing to remember is that there are no rules. It's all about you and your expression of yourself and having fun.

... on a first date with someone you think you like?
Wear a really fun dress in a light color to instantly draw her eyes to you.

… to radiate the energy of the main character?
Something like a monochromatic swimsuit with huge gold hoop earrings.

... to an event where you might meet your ex?
You should wear a really sexy little black dress. Black because you grieve that you were ever associated with such a loser.

… to stay with a rich mother?
Some really amazing long relaxed pants with a little crop top. Laid back but still a luxury, you know?
