This dress looks better when wearing, i am 5.8 regular size s or 6. cup 34 d and fits perfect. length and width. in the front is shorter while the back has that pretty extra length. the video that is showing here is pretty much the full length.  but in case you need to adjust you can shorten easily. i wish the slip is the same length as the dress. i want this dress for a wedding anniversary by the beach so i will need to add some extra fabric. i hope it helps.
