Christy Rilling is one of the fashion industry's quietly beavering talents, a woman whose behind-the-seams efforts have made stars from Jennifer Lawrence to Sarah Jessica Parker and Kim Kardashian look incredible in their clothes.


Rilling isn't a household name like many of the designers that she works so closely with, rather she is a tailor, a profession that usually conjures images of arch-backed old men wearing tweed suits and glasses. This 38 year-old New Yorker, who fits hundreds of stars for their red carpet appearances and Vogue covers each year, is, however, a significantly more glamorous poster girl for the craft than her predecessors.


"Everything can and probably should be tailored if you want to look amazing and if you want to look like one of our clients does in their clothes," she says of her ethos and the reason that half of Hollywood has her on speed dial.


"Many women don't know, or just forget that sizes off the rack are vague. Any annoyance that you may feel about not being a perfect size when you go shopping should just be thrown out of the window."


When Rilling says that anything can be tailored, she really means it. Some of the most simple requests that come in at her studio include tapering pencil skirts, adding new linings and altering trouser hems but, she says, her team can make anything look better, even your boots. "I see so many women walking around in over-the-knee boots that don't fit them at the ankle, or that hang around parts of the leg. You should get those tailored to fit your legs."


For her celebrity clients, entire garment re-builds are not uncommon, and she says that any good tailor should know how to pattern cut, too. "Adding sleeves is hugely popular," she says. "So many of the dresses that are designed for a woman over 40 don't have sleeves, and many of my clients simply want those added."


"Often if an actress is a plus size and she can't fit into the largest size that a designer makes, we will buy two and use the fabric to make one larger size," she divulges of what other requests are possible- and what you could ask a tailor to do for you too. "I also have clients who maybe wear a size 6 on the top and a 12 on the bottom, so we'll buy the dress in two sizes and merge them together."


For her regulars, Rilling is able to half their time spent in changing rooms by trying outfits onto her custom-made mannequins. "We build mannequins for each of our clients with their exact body measurements - it's like a sculpture of their body and we can make them gain or lose weight just as the person does in real life," she explains. "Often people will send us their shopping to try on their form and we can advise them what to keep and what to send back based on how it looks on their body."


The magic of great tailoring is that its effect is invisible - people will always pay a compliment to someone who looks incredible in their clothes, but they aren't always aware of why they look so great, or how much work it will have taken to achieve that effortless, perfect fit.


Possibly the most technically challenging piece that Rilling has ever worked on, she says, was the curve-hugging Atelier Versace gown that her client Michelle Obama wore to her final state dinner last October - made of rose gold chainmail, no less.


"It was made of a technique that only a few people in the world know how to handle," she explains. "Gianni Versace created this chainmail and there was a very specific way of putting it together. We had to study it and learn how to put it together and someone from their team flew over to help. You basically use little pliers and you unhook each individual chain, then put it back together that way. It was beautiful." The effort was worth it, however, as headlines around the world praised the 'dazzling' First Lady, who shined like a rockstar.


The impact of Rilling's work with Mrs Obama over the last eight years is not to be underestimated; in collaboration with stylist Meredith Koop, she has been part of the team that propelled the First Lady to style icon status. Look closely and great fit has, in fact, become a defining element of the FLOTUS's look.
