What makes a bedding set 'hotel style'?

Most reviewers we read describe hotel-style sets as crisp white or neutral colorways, sateen or percale cotton (or down-alternative microfiber for comforters), tailored pintuck or jacquard detailing, and a coordinated bed-in-a-bag bundle that includes comforter, sheets, pillowcases, and shams. The look is intentionally minimalist.
