Using lines in clothing to flatter your shape

Why lines matter more than you think

Every outfit you wear creates visual lines – whether it is a neckline, a seam, the finishing point of garment, a stripe, lapels, or even the way that colours are combined. These lines guide the eye, and where the eye goes, attention follows.

This means you can subtly reshape how your body appears, simply by choosing the right lines in the right places. Using lines intentionally means that you control:

  • Where you want the eye to go.
  • Areas that you want to lengthen or widen.
  • Creating a lengthening flow.
  • Breaking up areas that you want to minimise.

When you understand garment line essentials, you stop guessing and start dressing yourself in a very flattering way.

Vertical lines: creating length and elegance

Vertical lines draw the eye up and down, creating a sense of length and flow.

They are your go-to when you want to:

  • Look taller
  • Elongate your torso
  • Slim an area
  • Create a more streamlined silhouette.

What to look for

  • Longline jackets or cardigans
  • Centre seams or vertical panelling
  • V-necks and open necklines
  • Monochrome or tonal outfits
  • Full-length trousers.

What it best suits

If you feel an area looks shorter, broader, or more prominent than you would like, vertical lines help to visually stretch it.

When it does not suit quite as well

If your outfit is broken into lots of contrasting sections (for example, a light top with dark bottoms and a cropped jacket), the vertical effect is interrupted, and the body can appear shorter or more segmented.

Horizontal lines: adding width and balance

Horizontal lines draw the eye across the body, adding width and emphasis. This can be useful when you want to:

  • Balance proportions
  • Add shape
  • Create the illusion of curves, and
  • Broaden a narrower area.

What to look for

  • Boat necklines or wider necklines
  • Stripes across the upper body
  • Shoulder pads (to extend the line of a garment).

When best suits

If you have narrow shoulders or a small bust, horizontal lines can help create balance by adding visual width to your upper body.

When to be more careful

Placing horizontal lines across your widest areas (such as hips, thighs, or tummy) will naturally draw attention there and can make those areas appear broader.

The placement of lines is everything

It is not just about vertical versus horizontal — where the line sits on your body is what makes the biggest difference.

Breaking up larger areas

If you want to minimise or soften an area, the key is to avoid leaving it as one large, uninterrupted block. Instead, introduce lines that gently break it up.

Examples

  • A longline jacket over the hip area creates vertical movement and reduces width.
  • A wrap style across the midsection introduces diagonal lines that soften and flatter.
  • Seams, patterns in the right scale, layering, or subtle detailing help divide space from being one solid block.

What to avoid

  • Large areas of plain, unbroken fabric over areas that you prefer to downplay.
  • Strong horizontal lines sitting exactly on your widest point. This includes where your sleeves end.

Creating flow versus creating breaks

A key styling skill is knowing when to create flow and when to break it.

Create flow when you want to:

  • Elongate your body
  • Look taller or leaner, and
  • Create a more polished, elegant silhouette.

How

Keep colours similar or pair up colours (white blouse with white sneakers), use vertical elements, and avoid sharp contrasts.

Create breaks when you want to:

  • Define areas of the body
  • Stop the eye from focusing on one place, and
  • Add shape or structure.

How

  • Use layering, seams, or gentle contrast, but place them thoughtfully.

Confidence through understanding

The goal is to understand how to use lines as a tool. Once you start noticing lines in clothing, you will see them everywhere and you will know how to use them to your figure’s advantage.
