"Mad Men" costumer Janie Bryant always dresses the show's characters in captivating retro looks, so imagine StyleList's delight to find her looking as glamorous as one of the ladies of Sterling Cooper Draper Pryce.

Bryant greeted fans at the QVC pop-up shop in New York City to promote her new Janie Bryant MOD line for the shopping network and wore some of the collection's signature pieces, including a reversible teal swing coat, cascading statement necklace (with detachable brooch), and slim black cigarette pants.

The Emmy-winning costumer gave the ensemble a casual, updated twist with a crisp white T-shirt.

Despite being entranced by her animal-print handbag, we were able to squeeze in a chat.

StyleList: Is that your QVC handbag? It's adorable.
Janie Bryant: That's mine, and I really use it. I have been carrying it everywhere in New York, and it's a conversation piece. I was getting coffee and the girls in line were asking about it.

SL: You introduced your MOD collection on live TV during Fashion's Night Out.

JB: There was a huge crowd [watching the shoot]. I had done my on-air training the day before, and it was a closed set. I showed up [for the QVC appearance] and I was, "Oh my God, we are going to do it in front of all these people." But I was with [QVC host] Lisa Robertson, and she's so sweet and such a pro. I love all the pieces, so once I started talking, that kind of carried me.

SL: There's been such a response to the stylized "Mad Men" look. How did it influence this collection?
JB: This collection isn't about the show per se, but about the drama. It's about the glamour of the '50s and '60s. But it's also a modernization of those looks. I think of the collection as pieces you can incorporate into a modern wardrobe. Mix them with your own things for a look that can be vintage or contemporary.

SL: So if not from the show's costume closet, where did you draw your inspiration?
JB: From old movies and playing dress up as a little kid. Things of my mother's. Vogue magazines. Lots and lots of vintage Vogue magazines!

SL: Do you have a favorite piece?
JB: The [faux] snow lynx capelet. A cape is dramatic, comfortable, and cool. And they are versatile. You could wear it with jeans or dress up a skirt. I also love the accessories, especially the brooches. They are pretty cool because they are pendants, so you can put one on a hat or jacket, or do what I did and pop it on this big statement necklace for a more dramatic look.

SL: You have a new collaboration with Maidenform as well.
I am a spokesperson and there may be more to come in terms of doing a line. Shapewear is so important. A lot of women resist because of comfort. I'm trying to educate them that finding the right shapewear will provide them with the comfort they deserve and the shaping they need to look great.

SL: Let's talk "Mad Men." Peggy Olson is going through such a metamorphosis. How have you approached her wardrobe to reflect those changes?
JB: I actually can't talk about the individual characters, but I can say I am telling a story. There are changes happening in their lives, and I am reflecting those changes. I also approach each character thinking their closets are a lot like yours and mine. They add things, but they own things already. I allow myself to think my characters have their own vintage pieces, like we do.

SL: What inspired your new polishes for Nailtini?
Vintage fabrics. I wanted something very rich and dramatic. The inspiration was what I call "cocktail culture": silk, satins, and gold lamé. The color I have on is from my line, and it's Bourbon Satin.

SL: You are seriously busy. What's next?
JB: I have a new book coming out this fall called "The Fashion File." It's about inspiring you to find your own style, whether it's vintage, modern, or bohemian.
