There are very few trends more elegant than the ladylike chiffon gown, but one detail in particular has really transformed this look into something more this season- the side-split.

 
Second Grace Primevera Gown from Museum Mile

This tiny detail is set transform the 2015 prom dresses for this summer. Although it may appear slightly risqué, a little slit can go a long way, especcially with a maxi dress.
This trend is increasingly popular for one reason in particular - it makes your legs look seriously longer, perfect for anyone lacking in supermodel height (myself included!)

The side-split dress is a perfect dress for anyone who is confident with their legs. If there is perhaps another area of your body that you would rather not expose (For example, stomach in cut out dresses, a dress that shows the chest or a low back dress) this would be great for you. Being able to not only show off one of your favourite aesthetic aspects of yourself, whilst being completely on trend too!
