A plea for fashion advice

I've been on Weight Watchers for almost a year now, and I've lost over 40 lbs, with another 20-25 to go. If and when I get to my goal weight, I mean to splurge on a top-quality tartan skirt, something that will last me years and years, thereby motivating me to STAY at goal weight so it will fit me for book signings and whenever else I want to rock the Scottish part of my heritage.

What I'd really like is something like this:

Or possibly something in a more kiltish cut, like this:

But even being at goal weight is not going to make me look like the bonnie lassie modeling those skirts, and I want to make sure whatever I choose works for me. And I tend to look best in pencil or otherwise straight skirts. So maybe what I really need is this:

So, fashionistas...help me out. My heart is with the first two choices, because they're more evocative of a kilt. And I'm hoping the flat front of the second option would give enough of a straight skirt look to be flattering for me. But would I be better off playing it safe with a straight skirt?

And, while I'm at it...

Fraser Modern?

or Fraser Ancient Hunting?

(Assume I'd being wearing this with a black, dark brown, or dark green sweater and some silver Celtic jewelry.)
