Google defines a Cocktail dress as 'a smart dress suitable for formal social situations'. However that doesn't help me with the length. Whilst browsing Google I found an Ebay guide (see here) that had some handy hints for dressing in a cocktail dress according to your body type. It also stated that 'cocktail dresses have a range of lengths from a few inches above the knee to a few inches above the ankle'. I also found a handy little diagram (see here) that shows the names of those different dress lengths, all of which are included as 'cocktail dresses' excluding the floor length dress which I imagine falls under the evening gown category.
Now, knowing that, the dress I had in mind fits perfectly as it's in between tea length and ankle length. When it is almost touching the ankle it is supposedly called Ballerina length.My dress is an Autograph dress that I op shopped for about $5 from memory. I love how light the skirt is and how it flows which is great in this weather, unfortunately it shows quite a lot of cleavage which has stopped me from wearing it so much.
The shoes are from Target and are more than I would usually pay for shoes like this (especially from Target) but I've really been trying to find some black shoes that are dressier than thongs but not super dressy with a huge heel. These seem to fit the category so I bought them for $20 (which is apparently half price of $35 ?!?!) and so far so good.
Have a great one!
