Saw that Dissh has a 20% off coupon, which is valid on full priced dresses only, but still could get you far when it comes to value for money.
Dresses start at $40 a pop, and there are plenty of styles priced at $55, but shipping will cost you $5 on all orders below $50. The lowest priced dress will work out at a total of $37 delivered, meanwhile you can save almost $20 on more expensive styles.
One I have picked out was the Make Believe Asymmetrical dress (in the picture), which comes in a dusty rose colour. I like this dress as I think it would be perfect for autumn parties and as it's a new season style I don't have to worry about which sizes they've got in stock.
Available in all sizes from 6 to 14, this asymmetrical dress features a high neckline, a gathered waist with a tie front, and a keyhole detail in the back.
