  Ideas for a 21st birthday present for a female require a little more thought and effort than a regular present. A 21st birthday is a major milestone and your gift needs to reflect the importance of the event. It also needs to match the birthday girl's style and interests. A well-chosen item makes the gift highly appreciated and reflects the thought that went into its selection.
  
  

Bar Set

• A bar set is a common gift for 21st birthdays, for obvious reasons. A pair of freezable, themed beer mugs is an amusing and inexpensive gift. A basic beer set, with a pitcher and four mugs, is a useful and moderately priced gift. A fancy cocktail set, with four beer glasses, four cocktail glasses, four shot glasses, a pitcher, a cocktail shaker and a cocktail strainer, is a sophisticated and expensive gift.
  
  

Birthday Survival Kit

• Celebrating a 21st birthday often includes a night of wild drinking at assorted bars. If the birthday girl plans to follow this tradition, make sure to give her a "Birthday Survival Kit" before she heads out. The box can include labeled gifts, such as a shot glass on a stretchy necklace to "keep her from losing her drink," a small bottle of water and aspirin "for her hangover" and an identification bracelet "in case she gets lost."
  
  

Gift Basket

• A gift basket is a versatile birthday present that can work for any style or budget. A spa gift basket is ideal if the birthday girl enjoys pampering. The basket can include lotion, body scrub, bath beads, bath oil, bubble bath, pumice stones, loofahs and soap. A kitchen gift basket is very useful if the birthday girl is moving into her first apartment or house. The basket can include dishtowels, washcloths, potholders, hot pads, measuring cups, measuring spoons, placemats, napkins and a can opener.
  
  

Gift Cards

• Gift cards are popular birthday presents for more than just their convenience. A gift card lets the birthday girl choose her own item, which ensures the birthday present is perfect. Prepaid credit cards are a popular type of gift card and can be used almost anywhere. However, they tend to be boring gifts and are often used on dull items, such as groceries.
  
  Retail gift cards force recipients to have a little fun by focusing the money on a specific area. You can give a clothing store card to a fashionista or a bookstore card to an avid reader. Gift cards are available for many shops, including shoe, sports, electronic, furniture, music and pet stores.
  
  

Jewelry

• A beautiful piece of jewelry is a birthday gift that can be enjoyed for decades. The best jewelry presents are versatile items that suit a formal affair or a job interview. Expensive present ideas include a tiny diamond pendant on a gold chain, a pair of pearl earrings with a matching choker or a pair of small diamond stud earrings. Inexpensive ideas include a glass bead necklace with matching earrings and bracelet or a long metal chain with a turquoise pendant and matching earrings.
