I wouldn't, no. I've bought the same design in different colours a few times, but I've never bought exactly the same item. For one thing, I like not to repeat myself in terms of what I wear for regulars.

Yes , and I did

I’ve been wearing that first one until it was worn off , then chuck it and start wearing the new one 

Thank you ladies....

I do have other dresses but this one is just purfect! It’s silk so will get manhandled quite quick, it’s one of those dresses that looks smart, chic , expensive (well it is!) and will never go out of fashion. I can wear it in and out for dinner, change the shoe to give it a different look or even wear it casually with trainers.... I’m kind of selling it to myself
I got 2 but the first one is too big and I wore it so cannot return so for me it doesn’t count as having 2.

@ Kay, It’s not just for regulars for new people but regs wouldn’t  see me in same dress again.
@ Justine, Yes it’s the fade and manhandling , and I hate it when I like something so much and cannot find anything similar.
@Romily, How many did you get, Please share?? 
Wow Celeste, A dozen, impressive, I like this.
