Prom Dress Talk...

So lately every body's been getting their prom dresses and I'm stuck on which type of dress to get :( Red's my colour so I know I want a classy looking red dress but I don't want it to look tacky and want something different to what all my friends are going for, my choices are....
I was going to put a picture here... but the website I like the dresses on has some protection think where you can't copy and paste, save pictures or even print screen! So I'll have to put a link...

• This dress I love but I'm not sure how good it would look in red, http://www.lightinthebox.com/Sheath--Column-Straps-Floor-length-Chiffon-Evening-Dress_p185532.html
• I love the trail and strap on this dress, the shapes so unusual!...http://www.lightinthebox.com/Chiffon-Satin-Trumpet--Mermaid-One-Shoulder-Watteau-Train-Evening-Dress-inspired-by-Ksenia-Solo--FSA11342-_p161396.html
• This dress looks so elegant and I love how it's kind of strapless and kind of not?.. http://www.lightinthebox.com/Chiffon-A-line-Off-the-shoulder-Court-Train-Evening-Dress-inspired-by-Camilla-Belle--FSL0731-_p171408.html
• This dress is so classy and I love the vintage/ 1920's style of it! http://www.johnlewis.com/290844/Product.aspx

I have so much to choose from! ha ha, I love the low back/ back detail, because I think it's not the obvious thing that most people go for and can make a simple dress beautiful!

Hope this was helpful for anyone that's looking for something similar to me!
