Visit any department store website and you’ll find thousands of dress on sale. Your favourite brand may well be there but because the stores stock such a wide variety your size may not still be available. They tend to buy across the ranges rather than in depth.
The trick is to find a dress you like and then look for it on the designer/brand proprietary website where there is more likely to be a size range. You may or may not, of course, be lucky, and the earlier you start when the sales begin the more likely you’ll be successful.
Here are my picks from the sales - by designers such as Ted Baker, Max Mara Code, Vera Mont and Phase Eight. Don’t hang about though - here today…..gone tomorrow. For sure.
In terms of fit, side ruching and stretch will make a dress more flattering on a curvy figure. Ted Baker sizing is on the small side, a size 3 is a UK 12 or thereabouts.
