31+ Not Too Formal Not Too Casual. Pictures or links are helpful too i don't know if we have the same taste in clothes so, if you want something dressy casual your best bet would be forever 21. It may take place in a casual setting, too, like an outdoor café, park or sporting just as casual english would be inappropriate in more formal settings, formal english would sound out of place to your friends or acquaintances that.
This may be the perfect nye outfit.
@martino96 sounds good to me too You just want to choose a shoe that has a more of a casual vibe to it versus a similar shoe that is more formally built. Avoiding slang is also important, because slang is best suited for the everyday casual interaction, not a meeting with an important label executive. More photos around both articles would be good.
