Shoes very often make the outfit. They compliment the lines and proportions of any outfit, especially your bottom half. It is all about the silhouette! But some shoes are office approved, while others can be giving the wrong idea!
If you wear the classic trouser style to work, a medium heel is perfect. Lots of things will look good such as loafers, pumps, open toed and clothes. For sophistication, pointier shoes will look better while round toe will be more casual.
