Check the dress code

If the dress code is casual, choose some clothes that you would wear for school. A T-Shirt and jeans (not torn) are good enough.Sometimes, the invitation may say nice clothes only . For girls, choose a party dress and some classy jewelry to wear. Most hosts do not care about the dress code for boys, so wear the same thing in the Casual subsection.If you are invited to a costume party, choose a costume you can actually make. If you are lazy, you can make a quick costume from household items, but if you are willing enough, you can try to cosplay.
