I think your bags look great, I would be more than happy to receive one. I'm always the one that never ever brings a bag to put my stuff in.
I actually think the colours look okay, slighty different from the colour you showed them with, but unless you put them with the dressess, no-one will realise the difference. As everyone has said, spend the money on something else and give your FI a great big kiss for being so nice and understanding :-)
