This outfit was issued in 1997 under the Barbara Millicent Roberts Collection. The City Slicker outfit came with all the elements in the following picture (minus the doll and chain belt). According to the description on Barbie.com that piece was never included in the set so I’m relieved to know that I haven’t lost it.

Here is Poppy Parker in the outfit. Doesn’t she look beautiful? I may be biased but I can’t help myself 🙂
