Both women later changed and wore other designer outfits for the formal pre-G-20 summit dinner at 10 Downing Street , the British prime minister 's official residence . Wednesday morning , Sarah Brown wore a one-of-a-kind navy dress with red lining by the American-born Lintner , a spokeswoman for 10 Downing Street said . The designer specially made the dress in navy for Brown , but retails the garment in black for $ 720 , Lintner said . Michelle Obama 's outfit included a $ 158 green skirt and $ 298 bead and rhinestone cardigan from J.Crew , the store 's Web site showed . Brown also wore a pair of Astley Clarke earrings , according to a spokeswoman from 10 Downing Street . The Astley Clarke Web site sells earrings from less than $ 100 to more than $ 10,000 . The first ladies ' choices of outfits during this summit are being closely watched by the world 's media , both in terms of style and comparative cost . Both women pay for all of their clothes themselves and receive no clothing allowance , according to spokeswomen for both sides . Lintner first designed a dress for Brown for the British Fashion Council Awards in November 2007 , Lintner said . She sells to clients only through her West London studio and said she started her company out of frustration over the selection of workwear available for women . Although the clothes are expensive , she said , they are made to last . This is not the first time Michelle Obama has chosen an `` off the rack '' outfit . She has worn J.Crew before , including in American Vogue . When appearing on `` The Tonight Show '' with Jay Leno , she wore a J.Crew ensemble , on which she commented , `` You get some good stuff online . '' After the photo call , Obama and Brown visited Maggie 's Cancer Caring Center , where Brown is a patron . The spouses of the G-20 leaders have several events scheduled during their stay in London . On Tuesday , Brown will be host of a dinner for G-20 spouses . The dinner will take place at No . 11 Downing Street , the London residence of the chancellor of the exchequer , while the G-20 leaders take a working dinner next door at No . 10 . As well as the spouses of the G-20 leaders , prominent women in British sport , arts , fashion , charity and business are also expected to attend . Downing Street has said those invited are `` all intended to show off British talent . '' Those invited include `` Harry Potter '' author J.K. Rowling , supermodel Naomi Campbell and Olympic gold medal runner Kelly Holmes . Downing Street sources said Michelle Obama will be seated between Holmes and Rowling .
