Nute Gunray, Trade Federation Viceroy, opening of episode 1: Dark red double robe, with orangish sleeves (not the brightest orange), gemstone crest in silver tones (closest you can get)
Padme on Tatooine: blue flared cuff shirt w/ med grey trim, belted vest in grey with blue belt, standard boots, pantaloons in about 1 shade off darkest black
Jedi: belted vest, trim lined shirt in browns. Qui Gon wears dark brown pants, Obi-Wan wears light ones. For pants, crafter's pants look good when worn under a cloak, haven't tried with a vest yet.
Padme, arrival at Lake Retreat: Grand Ballgown, yellow top and either pinkish bottom or blue-purple (we can't have 3 colors like on her dress), I paired it with women's shoes as it looks like she's wearing flats, not pumps.
Padme, fireplace scene: black luxurious gown
Padme's wedding dress: intricate dress, ivory
Anakin: Black decorative vest, dark brown trim lined shirt, black high quality or uniform boots
Aylaa Secura (twi'lek jedi): Lekku wrap, revealing top, crafter's pants in either dark brown or black.
Leia at awards ceremony: Loose dress, both colors white, plated necklace
Luke at awards ceremony: Rugged jacket (I ended up using a shade of orange, the browns didn't pop like the color does in the film), brown comfortable slacks, black boots (high qual or uniform), black formal shirt
Luke on Hoth: Vested jacket tan with white sleeves, tan pants (large pocket pants work), grey cold weather gloves, panelled boots (white ribbings, with grey)
Han on Hoth: Scout Jacket, navy blue (or a shade or 2 off of black, we don't have navy blue), panelled boots w/ white ribbing, light blue body, white cold weather gloves. Swoop helm looks ok but can't really make it in the same colors.
Luke, Dagobah: Reinforced work shirt, large pocket pants in tans. Olive muscle shirt if you want to go more bare.
Bossk, Trandoshan bounty hunter: heavy flight suit in default colors
I have notes on a couple more but have yet to figure out which specific items match closest.
