When shopping for sundresses, you'll encounter terms like "A-line," "wrap," "shift," and "empire waist." Understanding what these silhouettes mean—and how they interact with different body shapes—is essential for building a wardrobe full of pieces you'll love wearing. This comprehensive guide breaks down every major dress silhouette, explaining what makes each unique and who they typically flatter most.

What Is a Dress Silhouette?

A silhouette refers to the overall outline or shape a dress creates when viewed as a whole. It's determined by where the dress fits closely to the body, where it flows freely, and how it creates visual lines from shoulder to hem. The same fabric and colour can look dramatically different depending on the silhouette, which is why understanding shapes is so fundamental to finding dresses you feel confident in.

While certain silhouettes are traditionally recommended for specific body types, remember that fashion rules are guidelines, not laws. The best silhouette for you is one that makes you feel comfortable and confident, regardless of what any style guide suggests.

Why Silhouette Matters

  • Creates visual proportions that can flatter your figure
  • Affects how comfortable you feel throughout the day
  • Determines what activities the dress is suitable for
  • Influences how formal or casual the dress appears
  • Impacts what undergarments work best

The A-Line Silhouette

The A-line is perhaps the most universally flattering and popular dress silhouette. Named for its resemblance to the letter 'A', this style is fitted at the bust and waist, then gradually flares out toward the hem. The gentle widening creates a balanced, feminine shape that works across virtually all body types.

A-line dresses work beautifully for sundresses because the flared skirt allows for easy movement and airflow—essential in Australian heat. The fitted bodice provides structure while the flowing bottom half keeps things cool and comfortable. This silhouette also transitions well from casual to dressy settings with simple accessory changes.

Best For:

The Shift Dress

Shift dresses hang straight from the shoulders with minimal waist definition, creating a column-like shape. Made popular in the 1960s, this silhouette remains a summer favourite for its effortless simplicity and incredible comfort. Shift dresses don't cling anywhere, making them ideal for very hot days or when you want to feel unrestricted.

The shift silhouette works particularly well for sundresses intended as beach cover-ups or casual daywear. Without a defined waist, these dresses can feel somewhat boxy on some figures, but adding a belt can instantly create more shape when desired.

Styling Tip

A shift dress can be transformed with accessories. Add a woven belt to create waist definition, or pair with statement earrings and strappy sandals to elevate the simple silhouette.

Best For:

The Wrap Dress

Invented by Diane von Furstenberg in the 1970s, the wrap dress features a front that wraps across the body and ties at the side or back, creating a V-neckline and a defined waist. This genius design is adjustable, flattering on most figures, and endlessly elegant.

Wrap sundresses are particularly flattering because the adjustable nature accommodates fluctuations in size—perfect for summer holidays when eating habits might differ from normal. The V-neckline elongates the torso, while the tie creates a waist at whatever point is most flattering for your proportions.

Best For:

The Empire Waist

Empire waist dresses are fitted from the shoulders to just below the bust, where a seam creates a high waistline. From there, the fabric flows loosely to the hem. This silhouette elongates the body by raising the visual waist and drawing attention upward to the face and décolletage.

For sundresses, the empire waist offers excellent comfort because nothing sits tightly at the natural waist or hips. This makes it ideal for active summer days, meals out, or anyone who finds traditional waistlines uncomfortable.

💡 Key Takeaway

Empire waist dresses create the illusion of longer legs by visually raising where the body divides. This can be especially flattering for petite women or those who want to elongate their silhouette.

Best For:

The Fit-and-Flare

Similar to the A-line but more dramatic, fit-and-flare dresses are fitted through the bodice and waist, then flare out significantly at the skirt. This creates a distinctly feminine, playful silhouette often associated with vintage and retro styles.

Fit-and-flare sundresses add movement and fun to summer outfits. The defined waist paired with a fuller skirt creates an hourglass appearance regardless of natural body shape. This silhouette is particularly lovely for garden parties, outdoor events, or any occasion where you want to make a statement.

Best For:

The Sheath Dress

Sheath dresses follow the body's natural contours from shoulder to hem without significant flaring. They're more structured than shift dresses, typically with darts or seaming that creates a defined shape while still allowing easy movement.

While sheaths are more commonly associated with professional settings, casual versions work beautifully as elegant summer sundresses. They're particularly suited to straight-shaped figures and create a sophisticated, streamlined appearance.

Best For:

The Maxi Silhouette

While "maxi" technically refers to length rather than shape, maxi dresses have become their own category with distinct considerations. These floor-length or ankle-length dresses create a dramatic, elegant silhouette that provides sun protection and a flowing, bohemian aesthetic.

Maxi sundresses come in various sub-silhouettes—A-line maxis, empire waist maxis, tiered maxis—each with different effects on the figure. When choosing a maxi, consider not just the length but the overall shape and where the dress fits or flows.

Maxi Dress Considerations

  • Proportions matter—petite women should consider where the waist sits
  • Lightweight fabrics prevent overheating despite coverage
  • High slits add movement and prevent tripping
  • Consider hemline length with preferred footwear

The Tiered Dress

Tiered dresses feature horizontal sections of fabric that create a layered effect from waist to hem. This bohemian-inspired silhouette adds volume and visual interest while maintaining a relaxed, effortless feel perfect for summer.

Tiered sundresses are inherently casual and playful. The horizontal lines and added volume around the hips mean this silhouette works best for those comfortable with added width in the lower half, though the right fabric weight and tier placement can flatter most figures.

Choosing Your Silhouette

The key to finding your ideal silhouette is experimentation. What looks perfect on a hanger or model may not suit your unique proportions, and conversely, a style you'd never considered might become your favourite once you try it.

Consider your lifestyle when choosing silhouettes. Active days call for forgiving shapes like shifts or A-lines, while special occasions might warrant more structured options. Your comfort is paramount—a dress that requires constant adjusting or conscious posture will never feel truly flattering, regardless of how it looks in photos.

Don't be afraid to step outside traditional recommendations for your body type. Fashion should be fun, and the best sundress is ultimately one that makes you smile when you put it on.
