Casual Silver Banshee cosplay

I've got several days of leave to take before the end of March so I've now got 3 or 4 day weeks for a while, which is great, and most importantly, allows me to nap on the sofa on Friday afternoons while I re-watch Smallville, which I'm sure most of you know I love.  Smallville is my go to telly series for when I'm ill or don't want to think, or have a lazy day planned, so I'm currently on season 10.  Today I watched:
Warrior (which had Lois in an Amazon Princess outfit which is glorious)
Persuasion, which had Lois gaining the values of a traditional 50s housewife, while still being quintessentially Lois
Conspiracy, which is really, really quite dark
and Escape, which has Lois and Clark on a romantic getaway, to the same place that Oliver and Chloe go to, not for romance, but for a dirty weekend.  It's also got the Silver Banshee, whom I love. Particularly, I love her costume, so I got to thinking what could a casual Banshee cosplay look like.

This is the traditional Silver Banshee costume:

Now because I like the aesthetic so much I would love to do a true to the comic version of this costume, but I'm not sure I'd ever have the confidence to wear something so form fitting.  I also have a thing for Marvel's Black Cat's costume (it must be the monochrome), and a while ago I saw a great casual cosplay on tumblr.

Long story short, I was inspired by Smallville's episode and the Black Cat costume to come up with a casual outfit for the Silver Banshee.
These are the rules I'm playing to:

• It's con casual, not everyday casual.  So it's something that needs to be recogniseable to other comic fans.
• The outfit must ape the banshee's costume enough to be recogniseable but must consist of ordinary clothes I would myself wear everyday.

I found these items online which I thought would work:

 

Hair extensions from La Demoiselle on Amazon

Bangle by Liquorish from ASOS - to be worn one on each wrist
Black scoop neck top from Dorothy Perkins
Monochrome Top from Asos collection
Skinny black lisbon jeans from Asos
Boots from this ebay seller - they are called Oxford Roma and come from China.  I'd rather people bought goods from a UK shop though.

At a con you'd want to do Silver Banshee makeup, then I think you'd be recogniseable. What do you all reckon?

Alternatives:
Instead of the jeans you could do black tights and a black lycra mini skirt.  Instead of the tops I've chosen you could do a tight black vest, but then you'd need to sew on white panels to approximate the Banshee's vest.  This version would probably only work for summer.

Things I have learnt:
I hate clothes shopping, even virtually, and even when it's costume related.
I don't know the terms for enough types of garments to search effectively.
I'm probably not cut out for these sort of posts.
