Remus was sure anything they had would be good for the party, he was also pretty sure that their hosts knew that over time clothes would have changed, they were invited after all.
"You want to go shopping before the party?" He tried so hard to resist those eyes, he knew he was fighting a loosing battle though. "Wouldn't we be extremely late if we did?" He could not fight or resist those puppydog eyes but he had logic on his side and he would at least try it.
He moved toward Sirius and wrapped his arm around his lover's shoulder. "Don't you want to look in your wardrobe first?" He would go get his mate anything he wanted of course but he hoped he could convince Sirius not to go out to a shop, going to that party was risky enough.
