Ad Agency Style Queen, Colleen Oberg

We love sharing with you our favorite customer’s tips to success and how they rock their personal style in the office. Meet Colleen Oberg, an Account Manager at a leading advertising agency. This is her style guide on how to keep it trendy in the city with a preppy twist.


I live in New York and I'm an Account Manager at Droga5, a leading creative advertising agency working with brands including Under Armour, Chase Bank, Johnsonville, YMCA, and Clearasil. I am originally from Washington DC and attended Colgate for College. My style is East Coast preppy with a New York twist. 

Personal Work Style.


Shop the Look       

Relaxed and cool.

I wear pants with a relaxed top and either a statement necklace or statement earrings most days.

In the summer, when I'm commuting in New York on the hot subway, I'm a big fan of dresses - the breezier the better. I wear sandals in the summer and flats or ankle boots in the other seasons.

Stilettos are a no-go for me but respect to the lady bosses out there rockin' the high heel.

How to Interview Style.

If a dress fits right, I'm all about the dress. The fewer pieces I have to shift around the better - worrying about your outfit looking just right in all it's small pieces is unnecessary stress when I'm already interviewing!

Advertising is a little more casual, so I've worn a chambray button-up tucked into a black lace pencil skirt with black heeled ankle boots.

Most awkward interview experience.

I couldn't print out my resume before my first interview, so I emailed the receptionists a PDF early in the morning, showed up resume-less, and they printed a few copies off for me before my interviews started. 

Travel. Any stories?

During my first two weeks at Droga we took a day trip out to Chicago and I met my clients in person for the first time after a 6am flight out of New York. We then stayed to have dinner with our agency partners and took another 6am flight the next day.

Beyond just coordinating all of the travel plans, both flights were miserable and required that I get through them looking put together and professional - not easy tasks! 

How to make it do-able.





 A comfortable but professional jacket to wear when flying - those trains and planes are AC ice boxes. I also never regret a scarf.

Flats - they take up so much less space in a carry on. 



Client Meeting Style.

In my industry, you dress for your client - for example, the tech industry, I wore jeans and a structured top with ankle boots or flats. For financial services clients, I might wear a fitted dress and more simple flats or heels.

How to Happy Hour. Summer Style.



It's summer now, so a simple dress with a medium-heel and a cool bag is my go to. Plus a killer necklace or earrings completes it.

You can find me with a crisp glass of wine or a vodka cocktail if I'm choosing.

Power look.

Put me in a flattering pair of dark jeans and black medium-heeled ankle booties that give you a little stomp on the office floors - any bad-ass professional woman out there gets a little bit of satisfaction out of that, I think. You look good and you gotta own it.
