Right now im using a longsword, but I just bought a danish longsword the 124 length one.
Gut instinct is something with 45-50 armor, mail mittens, light boots (Say Rus Cavalry?) and a heavy helm.
Say: Rus Scale, Klappvisier, Mail Mittens, Rus Cavalry Boots, Danish Greatsword. Not very original but basically the "concept" you want and solid. That might be expensive though, so if you don't have a cash reserve you might want to consider using an outfit with a total equip cost of 30K.
50K+ will likely cost you money and will certainly require a cash reserve.
40K is about enough to break even and maybe make some cash IF you have a large cash reserve.
30K is nice, few worries.
20K or less is for making money fast.
Just pick a "theme" and look spiffy
Leg Armor is not as important as the rest as an infantryman, and gloves are not too useful for the protection VS cost ratio and are only good beyond mail mittens if you are trying to save on weight.
