Many people try to use the McCall's M 4745 Civil War pattern for the tunic. I don't recommend it because the shoulders of the sleeve are weird. The instructions are also a little bit difficult to follow.

Some people use the Butterick B6340 pattern for the jodhpurs trousers.

I suggest using Hawk's pattern from the forum for the tunic.

If you want to use the McCall's M4745 pattern as a base I recommend following Char Tozard steps. He did a very good job with his uniform.

If you are searching the German ebay pages for boots  there are some key words to use.
 
The German word for boot is Stiefel.
The German word for leather is Leder. Don't be fooled by synthleder that's the not leather stuff.
NVA stands for Nationale Volksarmee and was the name used for the armed forces of the GDR. ( East Germany before the reunification)
 
 
knobelbecher ( will get you mainly the boots used for TIE pilots, the ones with the straps at the calf)
Seestiefel ( same as above but because people call the boots by different names it brings up different offers)
NVA Parade Stiefel ( this search will bring you the taller, straight shaft parade boots with no strap at the calf, these boots are generally shorter than riding boots but taller than knobelbecher although some people call them the same thing)
NVA Stiefel ( same as above but a broader search parameter)
Schaft stiefel ( this search will get you straight legged boots from right across the board. It's the broadest word you can use to search for the kind of boots most of the people here look for)
offizier stiefel  (This brings you officer boots from also right across the board and also from across many time periods and countries)
Reitstiefel   ( this is the word for riding boots and this is what you will get)

This page ( all in German) has an excellent size chart at the bottom for the various sizes ( normal EU, Bundeswehr, US, Uk and it will help navigate some of the standard sizes you will see.  If you are looking for riding boots or officer's boots you also need to consider calf width this is known as Wadenweite in German so if you are looking at boots this is the word to look for and the measurements will always be given in CM as Europe doesn't do inches. 
https://www.freudenberg-shop.de/shop_content.php/coID/15/item/14  Please note I'm not advertising this shop, it just has the best comparison table. 
By riding boots you will seriously need to watch out for synthetics as there are a lot of those mixed in with the leather ones. You can search for echt leder ( real leather) and that will narrow it down a lot. 

I hope this helps a bit.

You should not buy the Star Wars Imperial Officer Black Garbardine Uniform Costume that you linked. There are things that you would have to change on that one. For example it doesn’t have the modesty panel.
 
If you want to buy a Cosplaysky uniform, you should buy the Star Wars Imperial Officer Uniform Costume Deluxe Version NEW. It costs the same as the one you posted. People were able to go up to level 3 with that one if it was custom made for them. http://cosplaysky.com/star-wars-imperial-officer-uniform-costume-deluxe-version-new.html.
 
 
mwilsen was a little bit faster with his reply than me. 

Yes, for those reading this, please understand I 100% appreciate the hard work you are doing, providing caps at low prices.
Without your hard work we wouldn't have as many cleared officers as we do.
These are not easy to make, that is clearly illustrated by the fact professional companies have problems and compromise on the design.
It's most likely the reason this hasn't been broached before is because as we've said the subject is a little delicate and we may sound a little ungrateful, we're not.

I am now approved!!!

It's been a while! But I finally got the jacket back after commissioning it in October. Pants are still being worked on.
 

 

 

 

Congratulations!
