The strapless gown or cocktail dress has been popular this summer, but the VMA’s last night showed us that there is a new twist on this trend that is a bit more interesting and alluring – the one-shoulder dress. Rather than exposing both shoulders and leaving little to the imagination, the one-shoulder evening gown allows for that same sexy vibe by showing off some skin on one side, but is a little more coy by covering up the other. In addition, the possibilities for variety are more prevalent with the one-shoulder neck line. Some of music and Hollywood’s biggest names were found wearing this trend at last night’s MTV Video Music Awards.Britney Spears showed off some of that variety that I was talking about in a stunning dress by Julien Macdonald. The one shoulder cut out that went all the way down to her navel was sexy without being inappropriate or trashy and she looked quite elegant. Playing with neck lines like her allows for a seemingly simple dress of plain black to draw your attention. If you are looking for a way to spice up your little black dress, look for one with an interesting neck line like hers. One rule of thumb that you should always follow with a one-shoulder dress is that you never want to layer. You should never cover up that asymmetrical neck line with a cardigan or blazer. That is why this style is seen mostly in the spring and summer months when layers are not necessary. However, if you want to wear a one-shoulder look but be in something a little warmer, you could try a dress with long sleeves that only exposes the one shoulder rather than leaving an entire side of your body uncovered. Tove Lo wore an example of something like this last night with a Dion Lee piece and paired it with a pair of gold sneakers. She looked very comfortable, but also very feminine. One nice fact about this trend is that it works for both solid color dresses and dresses with patterns or bling. You can see an example of something solid where the neck line and the draping of the fabric bring all the personality to the look in Sasheer Zamata wore. But, you can see a contrast with the dress by Moschino that Taylor Hill wore. The sequins and sheer sections on Taylor’s dress were a lot to take in, but the rather simple angular neckline added something to the dress. Without it, the dress would have been too stuffy and heavy looking for a summer night. Another rule of thumb when wearing one-shoulder dresses is that you should wear very little jewelry, especially around your neck. If you must wear a necklace than you should make it a choker so as not to interfere with the neck line which is already a kind of ornamentation for the neck. Earrings are probably the best choice for jewelry to wear with a one-shoulder dress, because they can add a bit of sparkle without taking away from the dress. Both of the women above looked lovely without any bobbles on their necks. Both women also look quite good in their one-shoulder gowns because they have their hair up and away from their neck. Updos or short haircuts work well with the one-shoulder look because you can see the neckline and wearing your air up tends to elongate your neck and makes this kind of dress look even better. While the one-shoulder dress is popular with many celebrities and stylists, it isn’t for everyone. Women with large breasts might not look spectacular in this kind of dress because they are often tight across the bodice and larger breasts will look like they are being squeezed or like they might pop out. One exception to all of these rules might be the slouchy shoulder look. Kim Kardashian achieved the one shoulder look by pushing her John Galliano dress off of one shoulder. Even though she is a well-endowed women and was wearing a long dangly necklace with her hair down, she managed to pull off the one-shoulder look very well because she took a dress that was meant to be worn on both shoulders and just pushed one sleeve down.
