A pale wrap-look dress brings several clear lines together in this picture. The upper section falls diagonally towards an open neckline, with loosely cut long sleeves at each side. A broad decorated belt marks the waist. Below it, gathered fabric leads towards a high side slit while the rest of the skirt falls long. Pale open strappy shoes complete the outdoor view. The pose makes both the angled draping and the opening easy to see.
For a coat combination, concentrate on the belt. Close the actual coat over the dress and check the waist while sitting as well as standing. If the fabric pulls across the decoration, compare another fastening position or a roomier cut. The loose sleeves should also retain enough space inside the outer sleeves.
Then examine the outfit without the coat. The diagonal bodice and skirt draping direct attention towards the waist and onwards to the slit. Walk and sit to compare that opening in other positions. The image supplies a shape reference; whether the whole combination suits your arrival needs to be established with the garments you will actually wear.
