Socialite of the Month - Marrin Costello

Happy February, Socialites! We're so excited to introduce you to February's Socialite of the Month, Marrin Costello! This boss babe attended our LA workshop + we were immediately floored by her drive, passion + excitement to learn all things social. Since then, Marrin has been up to some incredible things + we can't wait to share them with you! 

Hi there! Tell us a bit about yourself and what it is that you do!

My name is Marrin Costello - and I am so many things.  I'm a creative director, business owner, coffee drinker, fashionista, powerhouse, foodie, stylist, vintage fur collector, nerd, compulsive organizer, flea market hunter, museum frequenter, art historian, hopeless romantic, world traveler, interior decorator, writer, editor, whiskey and tequila drinker, and sucker for anything sparkly.  I'm obsessed with my friends and family --- and consider them to be one in the same.  I love what I do, and never take a single day for granted.  I believe in the power of reciprocity, compassion, kindness and thoughtfulness, and always aim to make each person that I come into contact with feel like the best version of themselves --- both face-to-face and with the MARRIN COSTELLO brand.

Born and raised in the San Francisco Bay Area, I fell in love with making jewelry after being gifted a bead kit for Christmas as a child.  Said gift turned into a hobby and then transformed into a passion - and I have been designing accessories ever since.  I first sold my jewels at local craft fairs before the age of 10, and started bringing my one-of-a-kind pieces to local boutiques and gift shops to sell on consignment.  After moving to Los Angeles for college, I was sought after by a celebrity stylist and my work was credited on national television via American Idol.  It was in that moment that my eyes were opened to having a career path as a jewelry designer, and the vision I had for my future changed completely.  

Not knowing what to name my company upon initially applying for a business license, as every name I thought of at the time seemed too trendy and temperamental, I chose to register the company under my name (as that wasn’t sure to change any time soon) and do a DBA at a later date once I came up with another name more fitting than my own.  Well - that ‘later’ moment never arrived, and since then my name and my brand have become synonymous.

To date, my company has had international press and my jewels have been spotted on A-list celebrities walking the red carpet.  Using the company as a vessel for change, my team and I are also involved with charities and philanthropies nationwide, and continue to give back in as many ways as we possibly can.  Along with designing and launching seasonal and collaborative collections, as well as sharing my personal style through social media, I have also had the pleasure of art directing the entirety of the brand, and producing all of the events that corresponded to each collaboration and collection debut --- all of which can be viewed on the MARRINCOSTELLO.COM website under STYLING and EVENTS.  And as my personal style has evolved over the years, I have also been recognized as a tastemaker, influencer and style icon.


This resume is, of course, purely the highlight real of my business over the last several years. Because as most every entrepreneur will tell you, there are so many things that happen behind the scenes that often go unsaid --- long nights, early mornings, soul searching, breakdowns, breakthroughs, making weekdays out of weekends, and the occasional tear, just to name a few.  Through all of the ebbs and flows of running a business, I have come to realize that remaining authentic has been the most important and rewarding part of building a brand and running a company.  And this ultimately keeps both me and my brand centered and motivated.

How do you think your best friends would describe you?

I love this question. And I keep the most beautifully authentic and brutally honest people in my life to make sure that one, we keep each other in check, and two, to make sure that I am always being the most authentic version of myself - both in my personal life and with my company.

One of the most recent epiphanies that I had was truly processing the theory that, “We are what (and who) we attract.”  In meditating on the incredible friends and family in my life (and, I mean, INCREDIBLE) it was overwhelming to think that we are essentially reflections of each other.  And I was truly moved by what the people in my circle said about me - both in their responses to this question, and in simply being mirrors of each other.   I was completely humbled and honored to have had the following adjectives used to describe me: hard working, creative, focused, ambitious, passionate, diligent, futuristic, goal-oriented, purposeful, strong, generous, stylish, thoughtful, loving, sympathetic, intelligent, practical, feisty, funny, goofy, happy, magnetic, and a little bit crazy, among many others.  Needless to say, upon hearing this, my heart became exceptionally full.  Of all my accomplishments, I am the most proud of my relationships and the ‘gems’ that I have collected throughout the many chapters of my life.

So you’re a past Social Studio Shop Socialite. Can you tell our audience a little bit about what products or services you’ve participated in with what and us your experience was with those?

My experience with Shop Socialite was a complete game changer.  After attending the LA Workshop, Jessica (the founder) and her staff taught me to think about social media and marketing through a completely new and more comprehensive lens.  This workshop bridged the importance of creativity and strategy, and is a course that I reference often in continuing to improve the brand.  I always look forward to receiving the Socialite Newsletter in my email inbox, and am an avid listener of the podcast!

Before getting together with Social Studio Shop, what were your biggest struggles with social media?

Understanding how to leverage them for my business in an effective and focused manner.  Since taking the course, the lens through which I see and approach social media has become more refined, streamlined, and strategic.

Since starting your social media journey, what has been the biggest change you’ve seen in your brand?

Becoming more comfortable in being the face of the brand.  Hands down.  It might sound strange, as my business and I share the same name… but, as referenced earlier, my initial motive was not to be in the limelight.  It was purely to create beautiful conversation pieces for other people to enjoy and ultimately connect with others.  I was completely comfortable behind the camera as a creative director.  But alas, interest in my personal style, lifestyle, and the inner workings of the brand came about as a bi-product to the collections.  Social Studio Shop has given me great confidence in stepping into this new role.


Any exciting news you want to share with our readers?

Ooooo this year has already proved to be a HUGE one!  

I am so proud to have Social Studio as the first online publication to share the upcoming MC happenings, some of which include: launching the Resort Collection, debuting a new look for MARRINCOSTELLO.COM, releasing the MC blog, and debuting our first luxury collection - *just* to name a few!  Thanks to a lot of recent soul searching and reflecting in re-calibrating the purpose and mission of the brand, my team and I will be improving the design and structure of the company, refining the brand aesthetic and message, and truly making sure that I am communicating the best and most authentic version of myself as the ‘new’ face of the brand.
