Fantasie Bikini Size Guide: Tips for Finding Your Best Fit

Choosing a bikini that fits just right can make all the difference in how confident and comfortable you feel at the beach or pool. Fantasie swimwear is designed with support and shape in mind, especially for fuller busts. However, getting the correct size is essential to maximize that comfort and look. Whether you’re new to Fantasie or a loyal fan, this guide will walk you through how to find your best fit using the Fantasie bikini size system.


Understanding Fantasie Sizing: Bra-Sized Bikinis

Unlike many swimwear brands that use general sizes (like S, M, L), Fantasie uses bra sizing for bikini tops. That means if you know your everyday bra size, you’re already one step closer to your ideal swimwear fit.

Fantasie bikini tops come in:

  • Band sizes: 30–40+
  • Cup sizes: D–HH (depending on the style)

This system ensures that women with larger busts can find flattering, supportive swimwear without sacrificing style.


How to Measure for Fantasie Swimwear

To find your best size in Fantasie swimwear, follow these steps:

1. Measure Your Band Size

  • Wrap a measuring tape snugly under your bust.
  • Round to the nearest whole number.
  • If it’s an even number, that’s your band size. If it’s odd, round up to the next even number.

2. Measure Your Bust

  • Measure around the fullest part of your bust.
  • Keep the tape level and not too tight.

3. Calculate Your Cup Size

  • Subtract the band size from the bust measurement.
  • The difference corresponds to a cup size (e.g., 1 inch = A, 2 inches = B, 3 inches = C, etc.).

Example:
If your underbust is 34″ and bust is 39″, the difference is 5″ = DD cup.
Your Fantasie bikini top size would likely be 34DD.


Bikini Bottom Sizing

Fantasie bikini bottoms follow UK dress sizes, usually ranging from XS (UK 8) to XXL (UK 18/20). Refer to the size chart below for general guidance:

UK SizeWaist (inches)Hips (inches)
8 (XS)26–2735–36
10 (S)28–2937–38
12 (M)30–3139–40
14 (L)32–3341–42
16 (XL)34–3543–44
18/20 (XXL)36–3845–47

Tip: If you’re between sizes, consider whether you prefer more or less coverage in your bikini bottoms.


Fit Tips for Fantasie Swimwear

Choose Styles by Support Needs

  • Full Cup or Underwired Styles: Great for fuller busts needing maximum support.
  • Plunge or Bandeau Tops: Ideal if you want to highlight cleavage or avoid tan lines.

Adjustability Is Key

  • Look for bikinis with adjustable straps and back closures to fine-tune your fit.

Try Mix and Match

  • If your top and bottom sizes differ, Fantasie allows separate sizing so you can mix tops and bottoms to suit your proportions.

When to Size Up or Down

You might need to adjust your sizing depending on these factors:

  • If you’re between cup sizes: Try a sister size. (e.g., if 34DD is too snug in the band, try 36D).
  • If you prefer more coverage: Opt for a full-cup style or high-rise bottoms.
  • If you notice gaping or spillage: This could be a sign to go down or up a cup size.

Final Thought: Prioritize Fit Over Trend

While colors and patterns are fun, the best bikini is the one that fits like a glove. Fantasie’s bra-sized swimwear is specially crafted to support your curves, so finding the right size is the first step to feeling fabulous.

Confidence starts with the right fit—and Fantasie makes it easier than ever to find yours.
