Bikini Top Shapes Explained: How to Find Your Best Fit
By Celini Goulart
Trying a bikini for the first time and don't know which shape will fit you the most? Here's a complete guide on that.
Being a leading bikini wear brand in Bali, at ARUN Wear, we understand the frustration and confusion women feel while trying on a bikini top for the first time. Not only during online shopping, but even in-person trials confuse you when you don't know about the shapes available.
Once you understand that, shopping becomes considerably easier and considerably more satisfying. Let's learn about the topic in detail.
The Importance of the Bikini Top Shape
Yes, you heard it right. Most women already know their size. It is about shape, the cut, the structure, the way a top is designed to sit on the body.
The shape of your bikini top immediately makes or breaks your outfit.
At Arun's, we have a premium collection of bikini tops featuring distinct shapes, each designed with a specific kind of woman and a specific kind of day in mind. Here's how you can select the best one for yourself.
The Triangle Bikini Top
The triangle top is the one most women picture when they think of a bikini. It is the most versatile shape in the bikini world, featuring two fabric triangles, adjustable ties at the back, and a minimal design.
When to Choose a Triangle Bikini Top
The triangle shape works best when it has something to rest against. Here's when you can go for a triangle bikini top:
- To flatter your fuller bust by letting natural shape do the work.
- On a smaller bust, a triangle bikini top creates a clean, uncluttered line, giving you an effortless look.
- When you're looking for a top that tans evenly and best.
Simply put, if you are spending long days between the water and the sun lounger and want a top that requires nothing of you, the triangle is it.

- Available in three premium colour options: Chamomile, Blossom, and Lily
The One-Shoulder Bikini Top
Do you want to level up your beach outfit? There's nothing better than an asymmetric bikini top. Think of one shoulder shape. It's a design that gets noticed without even trying.
When to Choose a One-Shoulder Bikini Top
- If you want to break up the straight torso line and create visual volume.
- If you want to draw the eye across the body rather than straight down.
- One of the most supportive shapes in the bikini collection.
- Best if you don't want to change tops between the beach and a beach club lunch. All you need is to cover your one-shoulder bikini top with a contrasting sarong, and you are good to go.
Additionally, the single shoulder construction distributes weight differently from a standard tie top. This makes it a strong choice for women who want to actually swim in their swimwear.

- Made from recycled polyamide with a soft, silky hand
- Available in a range of colours: Black, Ocean, Coffee, Forest, Lavender
The V-Cut Bikini Top
This is a more specific shape, and it asks more of the woman wearing it. A V-cut bikini top is best for a beach club or late morning swim, where you want to feel comfortable.
When to Choose a V-Cut Bikini Top
- When you want a more defined décolletage. The V-cut neckline draws the eye inward and downward, making your neck appear longer.
- Best for women with a narrower frame, where the V creates a curve.
- Also perfect for women with fuller busts, since the V-shape provides optimal support

- The gold ring accent sits at the centre of the V shape, levelling up the overall look
- Comes with an adjustable clasp at the back to tailor your fit
- Available in Dark Ivy and White, two colours
The Crochet Bikini Top
In modern times, you can't ignore the importance of the crochet bikini top. The crochet top is the perfect blend of swimwear and craft. Moreover, in Bali, where the artisanal tradition runs deep, a crochet top is not a trend. It is a statement of understanding where you are and what that means.
When to Choose a Crochet Bikini Top
- Top adds a visual texture to the body without adding volume (open weave does it all).
- When you want a custom feel instead of mass-produced swimwear
If you are someone who believes that how something is made matters as much as how it looks, the crochet top is your answer.

The Structured Bralette Bikini Top
For the women who want to move freely, a bralette bikini top is the right shape. This shape borrows from lingerie but comes with wider coverage and more fabric.
When to Bralette a Crochet Bikini Top
- When you want to swim laps or take a surf lesson.
- For a proper, aesthetic beach vibe.
