A dark green diagonal-hem midi shows an uneven lower edge, side folds and one long sleeve as an additional upper detail in the outfit.
The lower line slopes from one side to the other, distinguishing it from an even broad hem curve. If that shape interests you, inspect a front and slight side view of the actual dress. Decide how you would like the unequal sides to meet your shoes. Show both shoes in a neutral stance before introducing a deliberate pose into the comparison.
The side folds add a direction above the edge. They do not establish a hidden wrap construction or adjustability, however. Describe the visible diagonal finish in a fitting conversation rather than assuming an undocumented fastening. That precision helps with discussing any potential alteration as well.
The asymmetric upper line and long sleeve can appeal separately. In this sequence, the dress primarily contributes a lower-shape comparison. Keep the shoe pair the same initially when changing to a straight midi. This helps identify what the sloping edge itself changes about the overall lower view you would like to choose.
