Size & Fit Advice

Mondor size conversion: The sizes shown on our website have already been converted from Mondor’s Canadian sizing to the UK gymnastics sizing used for The Zone. The original Mondor label inside the garment may therefore show a different size. Choose using our website size options and the size guide on this page.

Fit: A close gymnastics fit through the body, with broad shoulder straps. Compare your child’s measurements with the size guide, paying particular attention to torso girth. The converted size is a helpful reference; individual fit can vary between brands and styles.

Check torso length: Measure from the centre of one shoulder, down the front of the body, through the crotch and back up to the same shoulder in one continuous loop.

Try a gentle stretch: Ask your child to lift both arms overhead and reach out to the sides. The straps should stay in place, with no gaping at the neckline or uncomfortable pulling at the shoulders and leg openings. If measurements fall between sizes, ask our team for advice before ordering.

Mondor Gymnastics Size & Fit Advice

Mondor uses Canadian age-based sizing, which can feel different from the numbered gymnastics sizes commonly used in Europe. For the best fit, use the body measurements rather than choosing by age alone. For leotards, girth is particularly important because it reflects the full length of the torso.

Dance World Size Reference

From our fitting experience, Mondor's 8–10 generally feels closest to approximately a The Zone size 28. We use this only as a familiar reference for customers - it is not an official brand-to-brand size conversion.

Adult Mondor dancewear sizing uses S, M, L and XL. Compare bust, waist, hips and girth rather than converting directly from everyday clothing size.

Dance World Tip

Do not choose Mondor leotards from the age label alone. The Canadian age notation can fit differently from the European gymnastics sizing many customers are familiar with. Use girth first, then bust/chest and waist, and treat the age as a secondary reference.

Dance World Measuring Guide

How to Measure for Mondor Gymnastics Leotards

Measure over underwear or close-fitting clothing using a flexible tape measure. Stand naturally and keep the tape comfortably against the body without pulling it tight.

Girth

Key Measurement

Start at the centre of one shoulder. Bring the tape down the front of the torso, through the crotch and back up to the same shoulder in one complete loop.

For Mondor leotards, girth is the most useful measurement when age and body measurements suggest different sizes.

Bust / Chest

Measure around the fullest part of the bust or chest, keeping the tape level around the body without compressing it.

Waist

Measure around the natural waist, usually the narrowest part of the torso. Keep the tape comfortably close and level.

Hips

Measure around the fullest part of the hips and seat while standing naturally. Keep the tape level all the way around.

Height

Stand straight without shoes, with feet flat on the floor, and measure from the floor to the top of the head.

Mondor does not use height in this garment chart, but it can help when considering overall proportions and torso length.

Mondor Fit Guidance

Mondor's Canadian size labels can appear larger or smaller than expected when compared with familiar European age or numbered gymnastics sizes. Dance World therefore recommends choosing from the actual measurement chart rather than the age printed on the garment. Our familiar-size references are based on fitting experience and are intended to help customers interpret the chart, not replace Mondor's published measurements.

Dance World Fit Note Mondor size charts are intended as a guide. Fit can vary depending on torso length, body proportions, fabric and stretch. Dance World familiar size references are based on our fitting experience and are not official Mondor-to-brand conversions. Where measurements disagree, prioritise girth and overall body measurements over age.

Description

A Sparkling Start to the Routine

The Mondor Midnight 7851 girls’ sleeveless gymnastics leotard brings glossy stretch fabric and a sparkling rhinestone motif to classes, club training and display routines. Its classic tank shape combines broad shoulder straps, a round neckline and a scoop back, leaving the arms uncovered for reaching, balancing and practising skills. Curved rhinestone detail creates a sweetheart effect across the front, with a lighter scattering of sparkle below. A matching scrunchie is included, completing a coordinated gymnastics outfit for children who enjoy a little shine alongside a simple, familiar shape.

Mondor 7851 Midnight Sleeveless Gymnastics Leotard – Design & Performance

The 84% nylon and 16% elastane fabric gives the 7851 a smooth, flexible feel with a glossy surface that catches the light. The sleeveless cut leaves the arms uncovered, while the stretch body allows for reaching and bending. A comfort gusset adds a practical detail to the construction.

The sweetheart-style rhinestone motif sits beneath the round front neckline, with two curved sweeps meeting in a central dip. Smaller scattered details continue down the front, giving the design a softer finish below the main decoration. Broad shoulder straps frame the neckline, and neat edging follows the armholes and scoop back.

The plain back lets the fabric’s sheen stand out, keeping the sparkle concentrated at the front. As the sleeveless companion to the Mondor 7852, this style offers the same Midnight look for children who prefer a tank shape. The matching scrunchie brings the outfit together, making it easy to carry the look from the leotard into their hairstyle.

Product Highlight

✦ Sweetheart Sparkle in a Sleeveless Shape

The 7851 combines a glossy finish, curved rhinestone detail and the simplicity of a tank leotard. With the matching scrunchie already included, it creates a coordinated look that feels special for a display and brings a little extra shine to the weekly gym bag.

DANCE WORLD Parent Guide

Choosing a Leotard for a Display or Competition?

Ask your child’s coach whether the club uses a set team leotard or allows gymnasts to choose their own design. If you are buying specifically for a competition, check the event requirements too, including whether a sleeveless style and matching hair accessory are suitable.

Try the complete outfit before the day. Ask your child to reach overhead, stretch their arms to the sides and bend gently. The straps and neckline should sit neatly, with no uncomfortable pulling at the shoulders or leg openings. Include any underlayers or shorts they plan to wear when checking the fit.
