Kilt shirts come in two main styles: the regular dress shirt and the ghillie shirt.br Regular kilt shirts are button-up, structured, and perfect for formal events like weddings and black-tie dinners.br Ghillie shirts are lace-up, loose-fitting, and made for comfort, ideal for Highland games, ceilidhs, and casual wear.br Fabric choice plays a big role: cotton for crisp formality, linen for breathable tradition.br Styling differs too—ties and jackets with regular shirts, open-neck ease with ghillies.br Both have their place, so the choice comes down to occasion and personal style.
