Three button-down shirts

What I really love about my current wardrobe project is the opportunity to repeat a pattern until it's perfect.
Over the past week I applied myself to the McCall's 6035 shirt.  This is an armhole princess pattern with different pieces for A-B, C, and D bust sizes, and I was really looking forward to trying this canned approach to an FBA.

From the finished garment measurements, it was a toss up of either a 10D or a 12C.  They have almost identical bust measurements and only a little difference at the hip. Based on some of the previous comments I recalled from those of you that have already tackled this pattern and the climate I'm sewing for, I decided on the 12C.  Even if not sewing for an overheated environment,  and in this case overheated in so many different ways, I will always, always go for the looser fit - nothing says "trying too hard" than clothing that shows every lump and bump and undergarment line (yuck). I did stick to a 10 shoulder line and lowered the neckline to the 8.

You know what, I love it! Those deep princess lines I recall reading a few complaints about fit me to a T: they slide right over my BP.  It's a no-brainer that a lady with a smaller bust needs a shallow princess panel, and one with some frontal depth needs a deeper one.  Thank you, McCalls!

My first shirt, a wearable muslin made from a fairly coarse but wonderfully breathable navy-white-grey patterned cotton from the Fabric Flea Market, would've been perfect but for operator error.  The collar is not centred on the collar stand, and it's just obvious enough that I should (and will)  rip it out and re-insert (but not this month).  I also widened the back princess and side seams at the hem by 1/4", adding 2" to the overall hem.

As I was getting ready to cut my second iteration I remembered that patterns fit me much better when I shorten the back 1/2" between arm and waist. And what does that little adjustment do to the lower portion?  It flares the hem just so, which means I could've saved myself the trouble of widening the hem in the first iteration, because in the second shirt, it was not merely roomy enough, but plenty roomy.  But I don't mind. I plan on wearing them open over a tank top nine times out of ten, and I know they'll flap around me like the wings of an albatross regardless. 

In all three cases I made version C, the one with sporty rolled up sleeve and tabs to hold it up, but I lengthened the sleeve to full length (in case of being faced with a culturally-appropriate, overly modest setting) and also lengthened the tab to shoulder length, something I saw in a recent fashion show, and thought, cool -  a tab that's just a tad different! Each tab has two buttonholes and two buttons, one at the shoulder and the other at the bicep. The side benefit of this is I can lower the sleeve to not-quite-full-length, and button it into place with the upper buttonhole in the lower button.

They're not white.  They're very appropriate for the blue and olive and tan trousers I do have, however.

I have a little length of beautiful white linen, and another of a beautiful pale ice mint green linen that I'm just dying to transform into a couple of easy long sleeved tops, but I'm starting to suffer what I call "sewing brain freeze":  what to do, what to do, oh, which pattern?
