Finn loves bright, colorful clothing. Stuff he never got to wear or pick out in the FO. It delights him to no end. He looks ridiculous. And so, so happy.
Poe thinks it is ADORABLE and will FIGHT anyone who even looks like they're going to laugh at Finn and his clothes. Poe will buy every ugly neon-patterned monstrosity in the GALAXY if it means Finn can always be this delighted in just getting to pick out his clothes for the day.

Poe supposes this means he's in love.
