Well I just went through the entire thread and fixed all the links to my pics. WHEW!
So I'm happy to say that my Dress Blues uniform was a success at D-Con this year! Here are some very good pics:


And from the Parade itself:

So for the major changes here's a quick review:
The cover (hat):
The cover was originally a USMC Dress Blues white cover:

I removed the Eagle/Globe/Anchor device and replaced it with a custom USCM cap device made using a Challenge Coin:

The coin is attached to the cover with a screwpost and washer/nut combo:


The Tunic:

All United States Marine Corps insignias, and Eagle Globe Anchors (on the collar and buttons) were removed. The buttons were replaced with plain brass buttons. I gave the bottom pockets black buttons to create a bit more distinctiveness to the uniform steering it a little more away from genuine Dress Blues.
On the collar is custom Delta pins (you should be able to get a pair from Derek "CPL Smith" if he still has some left). Rank insignia are Army Dress Blue ranks. I permanently attached the Sulaco patch to the left breast pocket and the Screaming Eagle patch is above the left cuff. Dropship wings and campaign/merit ribbons finish off the impression.
The belt:

This is a white parade belt from Paradestore.com:
http://www.paradestore.com/detail.aspx?ID=92Choose white belt, brass hardware, with eyelets.
Pants are my Star Trek TWOK pants.
Basically black dress trousers with a custom added 1/2" red stripe.
Shoes are Oxford style dress shoes.
White parade gloves round out the uniform.
Now Kerri has asked about a female version. The floor is open to suggestions and it's pretty much up to yourself. Personally what I envision is a black blouse with a black knee length skirt:

This is a proposed new USMC female Dress Blues (not sure if it ever became current or not). As for a cover I would go with the current female service cap:
(photo removed by me)And switch out the Eagle Globe Anchor with a Challenge Coin.
Of course it's totally up to you!
Might be hard finding a genuine USMC blouse so you might have to find one that simply looks the part with a mandarin collar and have red piping custom added.
I look forward to see what you come up with!
Now there was also discussion of an alternate "B style" uniform (Derek Devildog was interested in putting this together).
The tunic and pants would remain the same. The cover would be a beret (black or red) and the belt would be a black leather garrison or Sam Browne belt.
Essentially it would look similar to this mock up:

(I'll take a better updated pic when I have the time to put my uniform on again

).
Best of success Marines!
