Question: Which fashion trend are the stars of "The Simple Life" known for wearing?
Context: Bug-eye glasses are a form of eyewear.  They were popular in the 1970s, 1980s and 1990s, and were used for regular glasses and sunglasses.  They first became popular in the mid-1970s, and succeeded the cat eye glasses of the 1950s and 1960s.  In the 1970s, they were more of a square shape, and then later evolved into the more characteristic, larger, rounder and more familiar bug-eyed style of the 1980s.  Their popularity began to decline later, as glasses became easier to get and more affordable.  They were fashionable for men and women and are still fashionable today but as retro sunglasses.  They were followed by the thick-rimmed, rectangular styled glasses of the 2000s.  Notable wearers are: Audrey Hepburn, Jacqueline Kennedy Onassis, Paris Hilton, Nicole Richie, Sophia Loren and Victoria Beckham. Simple Life is the fifth official EP by American duo Megan and Liz.  It was released independently on June 3, 2014, through Hidden Cow Inc, two months after the duo parted ways with their past record company, Collective Sounds.  The album marks the duo's shift toward a country-influenced sound, a departure from the pop influences of their previous material.  The EP was announced through an interview with Billboard magazine, when the duo revealed their split from Collective Sounds, and the title track of the EP, Simple Life.  The day the album was released, it went to number four on the Top Country Albums chart on iTunes. Ugg boots are a unisex style of sheepskin boot originating in Australia and New Zealand.  The boots are typically made of twin-faced sheepskin with fleece on the inside, a tanned outer surface and a synthetic sole.  The term, ugg boots, originated from Australia, initially for utilitarian footwear worn for warmth, and which were often worn by surfers during the 1960s.  In the 1970s, the boots were introduced to the surf culture of the United Kingdom and the United States.  Sheepskin boots became a fashion trend in the U.S. in the late 1990s and as a world-wide trend in the mid-2000s.  In Australia, they are worn predominantly as slippers and often associated with "daggy" fashion sense and "bogan" culture. Nicole Camille Richie (born Nicole Camille Escovedo; September 21, 1981) is an American fashion designer, author, actress and television personality.  Richie rose to prominence for her role in the Fox reality television series, "The Simple Life", alongside her childhood best friend and fellow socialite Paris Hilton, which lasted five seasons.  "The Simple Life" was a hit for the Fox network, premiering with 13 million viewers.  Richie's personal life attracted significant media attention during "The Simple Life"' s five-year run, and she was a constant fixture of tabloid journalism before and after her appearance. Wearing underwear as outerwear is a fashion trend.  Current examples include the display of thongs and bras in women's clothing, and the display of underpants under low-slung pants in men.  As of 2009, the visible wearing of corsets had become fashionable, popularized by stage performers such as Lady Gaga and Rihanna. A slouch sock is a type of sock popular in the 1980s featuring a heavy non-elastic upper that may be pushed down into heavy folds around the ankles or pulled up to the knee.  Slouch socks also tend to have a foot that is made of very thin fabric, to encourage layering of the socks.  A popular 80s fashion trend involved wearing multiple pairs of slouch socks to create a very thick, heavy slouching affect around the wearer's ankles. Paris Whitney Hilton (born February 17, 1981) is an American businesswoman, socialite, television and media personality, model, actress, singer, and DJ.  She is the great-granddaughter of Conrad Hilton, the founder of Hilton Hotels.  Born in New York City and raised there and in Beverly Hills, California, Hilton began her modeling career as a teenager when she signed with New York-based modelling development agency Trump Model Management.  Her lifestyle and rumored short-lived relationships made her a feature of entertainment news and tabloid magazines, and Hilton was proclaimed "New York's leading It girl" in 2001.  In 2003, a sex tape with Hilton and her then-boyfriend Rick Salomon, later released as "1 Night in Paris", was leaked to the public.  Released only three weeks before the premiere of the reality television series "The Simple Life", in which she starred alongside her long-time friend Nicole Richie, the sex tape became a media sensation. "Simple Life" is a song written by Elton John and Bernie Taupin and was the fourth single release from John's 1992 CD, "The One".  "Simple Life" was John's thirteenth number one on the Adult Contemporary chart.  The single spent three weeks at the number one spot and reached number thirty on the "Billboard" Hot 100. Leggings refers to several types of leg coverings.  Modern usage from the 1960s came to refer to elastic close-fitting garments worn over the legs typically by women, such as leg warmers or tights.  Usage from the 18th century refers to men's wear, usually made of cloth or leather that is wrapped around the leg down to the ankle.  In the 19th century leggings usually referred to infants' leg clothing that were matched with a jacket, as well as leg-wrappings made of leather or wool and worn by soldiers and trappers.  Leggings prominently returned to women's fashion in the 1960s, drawing from the form-fitting clothing of dancers.  With the widespread adoption of the synthetic fabric Lycra and the rise in popularity of aerobics, leggings came to further prominence in the 1970s and '80s, and eventually made their way into streetwear.  Leggings are a part of the late 2010s athleisure fashion trend of wearing activewear outside of sporting activities and in casual settings, which became a contentious social norm in the United States. Time* Sex* Love* is the seventh studio album from American country music artist Mary Chapin Carpenter.  It was released in 2001 on Columbia Records Nashville as her first full studio album since "A Place in the World" five years previous.
