So rough count we have north of 150 people on this forum alone that changed the dress for a custom one, counting these latest ones and the Yunsil one and a few that made their own customs. However designed the HT dress should feel a little embarrased.
Not really. They don't just make it up - they work form a resource.
If you look at Leia's costume in here https://blackwells.co.uk/bookshop/p...ZhegZLd0b0Xjeik7KAfvlBX_-ai0oLpBoCI2AQAvD_BwE you'll see that it's exactly the same. How many versions do you think there were? I'd reckon at least five - probably more. This version was exhibited as a prop from the movie and is likely the one they worked from. Whether it was actually in the movie is another matter.
Get the one you like best and style the figure how you want.
