... Why would you wear a jacket and then have a dress whose sleeves are so long? ...
That's what she thinks is the 'edgy style break' of her outfit.
You, Missy, are just a random fashion idiot unable to understand that Madame is a fashion expert with experienced experience in the subject.
Which is why she most often often wears repeats to fashion events (like today's trusted Rossis), plus some really weird thing - someone might have told her that a real fashionista mixes vintage with designer, hence what she does ...
(Her problem is that what would work as 'real' vintage has long been sold at Haberdash, so vintage in her closed is the 5-6 pieces older than 3 years).
ETA, I just saw in the other thread that the dress isn't 'designer', but H&M (and if you ask me, it does look 49 EUR at maximim, not 199 EUR).
So I revert my opinion above.
She donned the blazer to hide the hideousness of this shred ... because I have to admit, the blazer elevates it a bit. Pure, as shown by Peeds in the other thread, it's a disaster.
