Cynthia would have twirling her fork around at the piece of meat until she heard the words from Wallace. The words gave a little sting but it was the truth. She was usually seen as a boring champion, researching in her free time and doing nothing but that. However, she still had the chance to break free from those words. Boring on the outside but fun loving on the inside. She had a reputation of Sinnoh to keep after all!

"Thank you for your compliment Wallace. It's wonderful hearing such words from an extravagant trainer such as you." She'd press her her fork to her mouth, allowing the piece of meat to enter as she'd glance towards Wallace. Cynthia would just admire the fashion sense that he possessed, he was just so... Extra compared to her normal black coat outfit.

Wallace often kept most of his thoughts to himself, but he supposed being a bit honest to Cynthia won't dent their friendship. Newbie coordinators would be crushed by harsh criticism, so the man would usually praise them instead. Needless to say, it was a relief he could unwind like this. 

His male kimono was indeed fashionable, tailored with graceful curves and not in the traditional blocky shape. The man continues eating his salad, finishing his plate with neatness. "Its a pleasure, dear.", he raises his eyebrow and stares back with a teasing glint, "You seem to be staring a lot recently, did something catch your eye?"

"Yes, something did catch my eye indeed. Your outfit, I'm just wondering where I could get one handmade for me as well!" She'd look at her usual black outfit. It was getting old on her. "I've been wearing the same outfit for Arceus knows how long. I was thinking about changing it sometime soon! Perhaps we should go for a little shopping another day?" She gave a little suggestion, finishing off the rest of her meal.

Cynthia's outfit was dull and boring now. Although it was very fashionable the first time she wore it, it was becoming too linear. It was definitely time for a change. "Well! Thank you for the meal Wallace. Now, since our day is yet to end, how about we head to somewhere else for another activity?"
Jerry
"Nearly all my outfits are handmade, unfortunantly. Might be a long while before you can get a spot for my seamstress",he remarked, "Shopping is a great idea, since your, er, clothing doesn't seem quite wide"

While Wallace loved variety, he couldn't stand not having at least a bit of his signature color palette in it, hence why most of his clothes are personally made. He liked to admire designer clothings, but it was a bit late and a he yawned a bit, "The pleasure is all mine, thank you for allowing me to treat you like this. We can head over to the dance floor to relax a bit"
