Just place marking for the photo of you in it OP. I love the outfit. I know a Size 8 5ft5 woman in her 60s which amazing legs who could easily pull this off. But equally, I know plenty of 20-somethings it would look terrible on.
It's not age, it's body shape.
In my mid 20s I wore something similar (except not sparkly) and was told by my friend 'the top half's alright, but it's all gone wrong on the bottom half hasn't it, you look like a right slapper!" It was a lovely smart tailored playsuit that came to my mid thigh and my entire top half was totally covered, no boob on show at all, with tights and ankle boots.
My friend, was wearing a tight super short mini skirt with her knickers on show when she sat down, a bustier with her boobs spilling out the top, bare legs and platform stillettos.
I never went on a night out with her again. I phased her out after that. Nobody gets to tell me I 'look like a slapper" when wearing an outfit that has everything on show while I don't.
