How to Choose a Bikini Top for Your Bust Size

5 min read  ·  Fit guide  ·  A to D cup  ·  All four Elira styles

Buying a bikini top online without trying it first is a bit of a leap of faith. You are going off a photo, a size chart, and hoping the two line up once it arrives. The truth is, the size on the label matters less than the cut of the top. The same size can fit completely differently depending on whether there is structure, how the straps sit, and where the fabric actually holds.

This guide breaks down which Elira top works best at each cup size, and why. If you already know your size, jump straight to your section. If you are between sizes or unsure, start at the beginning.

Why the Cut Matters More Than the Size

Most women already know their bra size. The problem is that bikini sizing does not map onto bra sizing in any consistent way. A medium in one brand is a small in another, and neither tells you whether the cup shape will actually hold you or sit flat or gap at the sides.

What actually determines the fit is the construction: where the fabric sits, whether there is any internal structure, how the straps connect, and how adjustable the whole thing is. A top with ties gives you more control than one with fixed straps. A top with boning gives you shape without relying on thick padding. A simple triangle sits differently on a fuller bust than a structured cup.

That is why the same woman can love one style and find another completely unwearable, even in the same size. It is not the number. It is the cut.

Daphne: A Cup to D Cup

Daphne fits the widest range of all four styles, from A through to D cup. The reason it works across that range is the adjustable ties on the shoulder straps and at the back. You are not locked into a fixed shape. You pull to the tension that feels right for your size and that day, and it holds.

For smaller busts, the Daphne sits flat without adding bulk or creating a shape that does not feel like your own. It is unpadded, so what you get is a natural fit that moves with your body. For larger busts, the ties give you enough control to pull in coverage where you need it without the top slipping or pulling during the day.

It is also the most relaxed of the four styles. If you do not want structure or boning and just want something that fits and looks clean, the Daphne is the one.

Elyse: B Cup to C Cup

Elyse is the most structured style in the Elira range and works best from B through to C cup. It has an underwire that gives shape and lift without thick padding. The cup holds its form in and out of the water, so the fit you put on in the morning is the fit you have at the end of the day.

For B and C cups this is the sweet spot. The underwire gives you definition without overwhelming a smaller frame, and it provides enough support for a fuller bust without bulk. It is the style that tends to photograph the most cleanly because the cup keeps a consistent shape rather than shifting.

If you are a B cup who wants no structure at all, the Daphne or Ivana are worth considering instead. But if you want lift and shape, the Elyse is the one.

Arabelle: B Cup to D Cup

Arabelle is an underwire top that fits B through to D cup, and it gives the most lift of any Elira style. That comes from the tie front. You control how tight the shoulder straps sit, which lets you pull the fabric up and in to exactly the amount of lift you want. No fixed cup deciding for you.

The back fastens with a clasp, which holds firmly without loosening through the day. So the front tie gives you the lift and the clasp at the back keeps everything in place. For a smaller B cup that means a soft, pretty hold. For a C or D cup it means real security without relying on thick structure.

It is also the most romantic of the four styles. The tie front sits beautifully and the overall look is feminine. If you are packing for a trip where photos matter, the Arabelle is the one most people reach for.

Ivana: A Cup to D Cup

Like Daphne, Ivana fits A through to D cup. Where the two differ is in the strap. The Ivana has wider straps than a standard string triangle, which distributes the weight across the shoulder rather than concentrating it on one thin line. For larger cup sizes that makes a real difference in comfort over a full day.

For smaller busts the wider strap keeps the top sitting cleanly in place without the fabric moving around. For larger busts it takes the pressure off the shoulder and makes the top wearable for longer without becoming uncomfortable.

The Ivana also has the cleanest lines of the four styles, which makes it the easiest to wear as a top beyond the beach. Pair it with linen trousers or a skirt and it reads like an outfit rather than swimwear.

The Quick Version

If you want it in one place:

• A cup: Daphne or Ivana. Both fit A to D and work well without structure.
• B cup: All four styles fit. Elyse if you want underwire lift and shape. Arabelle if you want the most lift with a tie front. Daphne or Ivana if you want no structure.
• C cup: Elyse for structure and shape. Arabelle for adjustable coverage. Daphne or Ivana for a relaxed fit.
• D cup: Arabelle for the most coverage and adjustability. Ivana for wider straps and comfort. Daphne for a relaxed, unstructured fit.

Not sure on sizing? The Elira size guide has measurements for each style. If you are between sizes, the Elyse, Daphne, and Ivana all have adjustable tie closures. The Arabelle fastens with a clasp at the back.

A Note on Straps and Hardware

All Elira tops use metal hardware. This matters practically because metal holds its finish through salt water and sunscreen in a way that plastic hardware does not. Plastic rings crack and discolor after a season. Metal stays looking the way it did on day one.

It also matters for fit. The Arabelle fastens with a metal clasp at the back, which holds tension consistently and does not loosen during the day. The Elyse, Daphne, and Ivana all tie at the back, giving you the freedom to set the tension exactly where you want it. Either way, metal holds up through salt water and sunscreen in a way that plastic simply does not.
