What a fun way to spend an afternoon! And, good thing that your team's color is blue - because it is perfect for you!
Ok - for honest feedback, I'd suggest the following tweaks:
1) Let the jeans ride down on your hips a little bit lower - maybe loosen the belt a notch or two and pull the jeans down?
2) The white jacket is a great idea - but, (and please keep in mind that this is only my UN-expert opinion!) I think that it looks dated. I'd try a more fluid or oversized type of white jacket with this outfit - something not quite so teeny-tiny looking. Also, I think that it would look more flattering if the sleeves were not the same length as the jacket - see what I mean how the sleeves and the bottom of the jacket are "cutting" a horizontal line across you? I'd push the sleeves up - so that they are not the same length as the jacket.
3) And, one last thing I really like a large cuff on slouchy skinnies and/or regular skinnies, but I think that a BF jean looks much better with a pegged roll than a large cuff. The pegged roll brings some structure to the jeans and reigns in the bagginess. (See how the model has her jeans rolled? That's what I'm talking about!)
P.S. Love the sunnies!
