I didn't look to Trowa's other clothing in the series since ultimately all of those clothes are issued uniforms. Still, most of the clothes he winds up wearing are rather flattering on him. Thus, why not showcase them? They may or may not be of his personal preference, but he does look sharp.
☆ Antarctica Snow Coat - Interestingly it rather complimented his usual look. It was nice to see him in such lighter colors and the green collar combined nicely with his turtleneck.
☆ OZ Uniform - One might as well say the green OZ uniform was made for Trowa. It is one of the best outfits he has worn in the series. The dark green with the crimson and gold adornments really suited him. He looked almost distinguished.
☆ OZ Space Suit - The OZ space suit actually was an okay color for Trowa. It would have been better if it had a greater saturation, but it gives an idea as to what he can really look like in lighter shades. He really should add in some lighter shades of green and blue to his wardrobe.
☆ Shuttle Space Suit - Yes, yes... it is pretty much an astronaut suit, but it does show that Trowa still can pull off brighter shades. Really, some brighter colored shirts wouldn't hurt him... as long as they aren't fire engine red, tangerine orange, lemon yellow, pink, or lavender.
☆ Fighting Space Suit - Again, this space suit was made for him... and pretty much the other four Gundam Pilots. The fit shows off his body nicely, the colors compliment and are very masculine. The fact that he has the dark blue combination rather than the dark gray is great as well.
