LAFC: Adidas logo centered. Crest centered below Adidas logo. FLEX power tools sponsor. All gold.
Main design is Black with dark grey/silver patterns similar to/including the ones seen in the archway here (but a bit more diverse with the clusters of diamond shapes and fan shapes):
Could be a direct reference to some architecture maybe but I was not told exactly what it was.
Round collar w/ gold trim. Gold shoulder stripes. Gold sleeve trim around the sleeve cuffs in the 3/4 style. Black back.
Red Bulls getting red is nice except that most teams are still getting a quite solid colored kit from what I've seen so far. I'm getting a sort of NFL Color Rush vibe across the league which, to me, says Adidas trying to make simple kits, but louder base colors.
Dallas: this pattern horizontally four times, getting a bit smaller height-wise as you go further down the shirt. The first one goes through the logo and crest and is slightly taller than the crest. Round collar with blue trim. Blue shoulder stripes. Blue back. Fabric stripe up the sides and onto the sleeves is blue and back is red.
Philadelphia Union - Navy with light gold trim/adidas logo & gold adidas stripes. On the front there's a vertical stripe that passes through the team crest, a bit thinner than the crest. Stripe is light blue with a pink-ish peach tone stroke on the left and right edge of it. Stripe is barely thinner than the crest.
