Black pants, dark red tunic, blue tabard and capelette, blue beret. Sadly, no, there will not be any commercial patterns one can buy that will be exactly this outfit.
The gloves are long gauntlet style (they may have a proper name buy buying these is unlikely). The boots are over-the-knee or Cavalier style. Buyable but really expensive. Like seriously expensive. I'll address both garments further down the post.
The beret can be bought, probably fairly cheap too. I'd buy it FIRST
, then get fabrics to match it. There are many more color options in broadcloth than there will be in wool berets.
There are some basic tabards in some costume patterns, but as much as you'll have to change it it's not worth the money. The good news is tabards are essentially rectangles that just hang over the body. Drafting it will entail taking your measurements and drawing a rectangle that will sit on you in the same proportions (yay for normally proportioned characters!)
The capelette has a fancy collar so seeking out a pattern is worthwhile. You may have to go vintage and I'm 99% sure it'll be a ladies pattern, but no one will be the wiser after your costume tweaks.
The tunic and pants are so covered up, you may be able to just thrift buy both.
Back to the boots and gloves...
I would seek out boot cover patterns and make them in an off white or pale gray ultrasuede (it's fake leather. Sews beautifully). Then buy some white gloves and make gauntlets from your same ultrasuede. You can leave them as separate or sew to the gloves, doesn't matter in the worn costume only your dressing. I would sew a patch onto the backs of the hands for more color continuity. Or paint or dye the gloves to match the suede, but I think sewing is easier.
