Workwear That Works For Everybody.
And Any Body.

Of Mercer Co-Founders

Making cool, confident careerwear up to a size 12 just wasn’t enough.

When we started Of Mercer three years ago, we set out with the mission of making professional women look and feel their best in and out of the office. But as a small company we had to start...well, small - offering only 7 sizes in our desk-to-dinner styles. But we knew this wasn’t enough.

Over the past few years, it has become abundantly clear that we have many more women who we need to serve. We hear from our would-be customers regularly, asking for us to increase our size range, and it has become all too obvious that many fashion brands are completely ignoring women over size 12, especially if you demand something better than fast-fashion (you should!). So we knew it was time for us to step in and do something about it.

But either was scaling our size 6 fit upwards and upwards.
We wanted to make sure our plus fit did women’s bodies justice.


So we crowdsourced all of the issues with existing plus sizes.
And we scienced the sh** out of it.

As a data-centric company (duh, we have Wharton founders) we set out to talk to anyone who would speak to us about the challenges facing plus-size women. We spoke with 50+ professionals (lawyers, bankers, doctors), plus-size experts, models, influencers, and even Janet a high school principal who sat next to Dorie on a plane to Raleigh-Durham. We have enough notes to write a book about fit concerns – arm holes, chest circumference, hem length, and so many more.

With these women we narrowed down the 10 silhouettes to focus on to launch our line, and then we re-fit them through many iterations with a size 16W fit model (Elizabeth Taylor who you may recognize as Melissa McCarthy’s right-hand woman). There are so many subtle, but important, updates from our straight size fit. For example, The Hudson Dress has a sleeve stitch that can be snipped if you want a little more wiggle room for your arm. But this is just the beginning. We are excited to get feedback from our customers and to continue to offer more styles in extended sizes.

And found ourselves joining a movement that was bigger than us.

You may recognize some of the faces of our line. Clémentine Desseaux founded the All Women Project, Katie Sturino is a plus-size fashion expert and founder of The 12ish Style, and Julie Henderson launched ALDA with four fellow models (including Ashley Graham) when Ford Models shut down its plus size division, despite it being the most profitable. We are proud to join these, and so many other women in the movement towards size inclusivity and body positivity.


How thoughtfully-designed are our extended styles? Very.

When we interviewed over 50 women, we took what they had to say very seriously. We made sure that our plus styles addressed their most pressing complaints. While some of our fixes are obvious (duh, fabric should not be itches), others are subtle and might we add, downright genius.

Designers Fix

The Complaint: Sleeves are restrictive

The Fix: We added ease at the sleeve cap to allow for maximum movement and comfort. On the Hudson's cap sleeves we tacked down an extra 1" that can be released for even more room.
Designers Fix

The Complaint: Hemlines are too short and ride up when walking 

The Fix: We lengthened certain silhouettes to ensure dresses don't bunch up when you're walking. The lining is also secured at the hem so it stays put as well
Designers Fix

The Complaint: Armholes are too low and revealing or too high and uncomfortable 

The Fix: We reshaped the armhole to ensure your bra never shows and the armhole never cuts into you for coverage and comfort.
Designers Fix

The Complaint: Cheap, itchy fabrics

The Fix: We use premium European and Japanese fabrics. All durable, resilient, machine washable whenever possible, and with a hint of stretch.
Designers Fix

The Complaint: Styles are either too revealing for work or are boxy and unflattering

The Fix: We have always been committed to making sure women can dress for work while still feeling like themselves and our new sizes are no different. Each style has been meticulously tailored to hug and accentuate curves while and look office appropriate.
Designers Fix

The Complaint: Garments are cheaply made and don't hold up

The Fix: Our fabrics our durable and our clothing is all produced in NYC's garment district. These clothes are built to last.
