Look at the pic. Its a coat with a bow in front over a dress. It looks like the dress has a little bit of drape in front. It doesn't look like a so-called shield or hankerchief after all.
OMG. The shoes are wrong for this dress. The cleavage is wrong for a First Lady in the daytime. The dress is bad...like the inaugural dress, and the color is WRONG.
It also appears that she does not have any hosiery on. Very tacky when dressed up!
