New York, January 21 : Fashion pundits can stop scratching their foreheads trying to figure out what kept First Lady Michelle Obama from freezing in her Inauguration Day dress, thanks to the revelation that her outfit hid `extra warm linings'.

The First Lady had sent minds racing when she clad herself in a pale yellow dress, matched with a coat made of Swiss wool lace and lined with French silk by Cuban-American designer Isabel Toledo.

The dress, which was paired with a set of contrasting emerald green stilettos, was further bejewelled with a diamond brooch and studs.

"(The outfit) was made for Michelle with extra warm linings sewn into the [innerlinings] that she wouldn''t freeze," the New York Daily News quoted Toledo''s husband as saying.

A spring version of the inaugural outfit, to cost buyers around 1500 dollars, will be made available in US department store Barney''s in March. (ANI)
