@Gabs28 you're welcome, I may be wrong but I don't think we can find some dress that is exactly like the one in your pic, but you can take an eye on some of the older outfits at Lianasims, there are some meshes there, you could make with ease a recolor that gets closer to what you're looking for, pay special attention to the dresses based on her meshes 005, 010 and 012 just to suggest someones.

Later you can look for a cape as accessory to round the look.
From now on I'm just a lurker, the sad truth about the Orwellian status of the sims community is not "off-topic" neither is "politics".
