How to Guarantee Your Competition Bikini Fits Perfectly by IFBB Pro Cassie

A perfectly fitting competition bikini is one of the most important parts of your stage presentation. You've spent months/years building your physique, so you want to make sure your bikini showcases all of your hard work in the best possible way!
I've worn a variety of competition bikinis throughout my time competing, and I've learned that there isn't one 'perfect' style for everyone. The best bikini is the one that's designed around your physique, your proportions, and the look you want to achieve on stage.
Here are my top tips for guaranteeing the perfect fit.
1. Choose the Right Bikini Top Style
One of the biggest decisions you'll make is whether to choose a moulded cup or a soft triangle cup. Both styles work beautifully and both enhance your natural shape, so there isn't a right or wrong choice.
A moulded top creates a more structured, balanced and symmetrical look. The firmer cups hold their shape and can give your overall presentation a polished, classic competition appearance.
A soft triangle top offers a softer, more natural look that's similar to a beach bikini. It moves more naturally with your body and creates a slightly different stage aesthetic.
I've competed in both styles over the years, and honestly, I love both. They simply create a different feel to your overall stage look, so choose the one that matches the image you want to present.

2. Select Bottoms That Complement Your Physique
Competition bikini bottoms are highly customisable, and choosing the right style can make a real difference to your proportions.
Think about:
- Rounded front or V-front?
- Pro-cut back or more coverage?
- Higher rise or lower rise?
Again there isn't a correct answer - it's about what flatters your body.
If you're carrying a little more softness through the glutes, you might feel more comfortable with slightly more back coverage.
If you're stage lean with full, developed glutes, I often recommend a pro-level back. This allows you to showcase the roundness and fullness of your upper glutes without unnecessary fabric covering your hard-earned shape.

3. Accurate Measurements Are Everything
Even the most beautiful bikini won't look its best if it doesn't fit correctly.
To accentuate your proportions, your suit needs to be made specifically for your body.
For example:
- If you have a longer torso, you may prefer a slightly higher front rise to create a more balanced look.
- If you have a very small waist and shorter torso, a lower front rise may complement your proportions better.
This is why accurate measurements are so important:
How to measure Crotch Length
Put on a bikini that you're comfortable wearing.
Using a tape measure, pull the tape firmly - not loosely - from the top of the bikini at the front, through your legs, to just above your butt crack at the back.
The tape needs to be pulled taut because competition bikinis are made from elasticated fabric. This measurement allows Dream Bikini to create a suit that fits securely without sagging or pulling.


Widest Glute Measurement
Measure around the fullest part of your glutes.
This ensures your bottoms sit comfortably on your hips without rolling down while still giving the snug fit that's expected from a competition bikini.
Show bikinis are designed to fit closely, so accuracy really matters.


4. Don't Be Afraid to Customise
One of the biggest advantages of having a custom-made competition bikini is that it can be tailored specifically to your needs.
For example you may want:
- A slightly wider gusset.
- A higher front rise.
- Extra coverage over a C-section scar.
- Adjustments for your unique proportions.
Dream Bikini are always happy to accommodate these requests wherever possible.
Simply place your order as normal, then email info@dreambikini.co.uk with your order number and details of the adjustments you'd like. The team will work with you to create a bikini that's made specifically for your body and your goals.
Final Thoughts
A competition bikini should never be an afterthought... The right fit can enhance your proportions highlight your physique, and give you the confidence to walk on stage knowing you're presenting the very best version of yourself.
Remember there isn't one perfect style that suits everyone. The goal is to choose the cuts, coverage and measurements that work for your physique.
You've put in the work to build your body - make sure your bikini allows it to shine.
