Go for it!

Some will disagree...who cares!?

Some ideas:

Wear stockings (sexy or classy...or both)... goth boots or (high) heels, no sporran! maybe no belt or a nice fashion belt...a nice blouse.
Maybe it's nice to use a sporran as a handbag?

I think women wearing a tank can look extremly good...just don't dress the way "us men" do.

It's hard to give good advise...what looks good on one person can look terrible on another...and personal taste and style is also an issue.

Anyway...GET your tank, after that you can start fiddling around with the rest of the outfit.

Good luck!
