Okay, I'm going to take a stab at sorting out the suits and candle shots from meet and greet to FRC.
Meet and greet-rose ceremony 1: I'm not convinced that the second photo is the same suit as the meet and greet suit. Plus, it looks the same style and cut of suit for rose ceremony 4 and rose ceremony six?
2 group dates-rose ceremony 2:
2 one on one dates and rugby-rose ceremony 3:
1 one on one; 1 two on one and 1 group tennis date-rose ceremony 4: I think it's possible he wears this suit here. He wore a brown suit the week before and, while this one appears to also be brown, I think he'd be more likely to wear something blue (like the shirt).
Idaho group date-rose ceremony 5: It's possible that this might be the Idaho rose ceremony suit. It's still up in the air for me as to whether or not this might also be a hometown date.
Hometown dates-rose ceremony 6: I think it's possible that he wears this outfit this week. The only thing that has me stumped is that the suit jackets look exactly the same for rose ceremony 4 and rose ceremony six. The only thing different is the shirt and tie.
Fantasy dates-rose ceremony 7:
No clue what suit/outfit he might wear but I'd expect it to be a cooler style.
Meet his parents and FRC-rose ceremony 8:
I think this might be taken at his parent's home.
This is FRC suit.
Would they really fly to Barbados and then to Britain and then back to Barbados?
