Lingerie Size Guide

How Our Sizing Works

Most of our pieces are sold as sets, which means the top and bottom come together in one size.

Because of this, not every style will suit every body perfectly — and that’s completely normal.

To make sizing more flexible, many of our styles include:

  • adjustable straps for bust support
  • stretch fabrics that move with your body
  • sliders or adjustable details on briefs and G-strings to help customise the fit

If you need a little more room through the bust, it’s often best to size up — the adjustable features usually allow you to bring the rest of the fit in where needed.

Fit isn’t just about the size on the label — it’s about how the piece sits and adjusts to your body.

📐 How to Measure

Underbust
Measure around your ribcage, just under your bust. Keep the tape firm but not tight.

Bust
Measure around the fullest part of your bust. Keep the tape level and relaxed.

Use these measurements as a guide — not a rule.

What a Good Fit Should Feel Like

A well-fitting piece should:

  • sit flat against your body without digging in
  • feel supportive without feeling tight
  • stay in place without needing adjustment
  • feel comfortable enough to forget you’re wearing it

If something feels off, it usually is.

Small issues — like straps digging in or fabric sitting wrong — are usually signs the fit isn’t quite right.

If You’re Between Sizes

Go with the size that:

  • feels more comfortable
  • sits more smoothly
  • doesn’t require constant adjusting

There’s no “perfect” number — only what works best on your body.

If Your Body Has Changed

Bodies change — and lingerie should work with that, not against it.

If your shape has shifted (post-baby, weight changes, or just over time), focus less on your old size and more on how pieces:

  • sit
  • support
  • move with you

If you’re unsure where to start, styles from our Contour Collection are designed to be easier to fit and flatter your shape.

🤍 Still Not Sure?

If you’re unsure about sizing, you’re not expected to figure it out alone.

You’re always welcome to get in touch — Tamara can help guide you based on your shape, what you’re looking for, and how different styles tend to fit.

If your local or near to the Sunshine Coast, QLD,  book a private fitting.

Tamara is also available for 15min zoom virtual fittings.

In Detention puts a cheeky twist on the classic student costume, combining glossy black wet-look fabric with playful red-and-black tartan detailing.

The cropped, sleeveless top features a flattering scoop neckline, a decorative letter patch and a tartan underbust band. A matching pleated mini skirt brings plenty of attitude, with a coordinating tartan waistband and attached suspender straps to complete the look.

Add the matching tartan neck bow for a little extra mischief. Perfect for adult costume parties, playful roleplay and anyone who enjoys dressing up with a rebellious streak.

Available in both standard and curvy sizes, because a little trouble looks good on everyone.

Key Features

  • Glossy wet-look finish – striking black fabric with a smooth, high-shine appearance.

  • Cropped sleeveless top – scoop neckline with a decorative letter patch.

  • Red-and-black tartan trim – coordinated bands at the bust and waist.

  • Pleated mini skirt – a playful, flared silhouette with plenty of movement.

  • Attached suspender straps – ideal for pairing with your favourite thigh-high stockings.

  • Matching neck bow – a finishing touch that ties the student-inspired look together.

  • Two size options – Standard S–M (AU 8–12) and Curvy L–XL (AU 14–16).

Why Buy: For a playful costume that combines classic tartan, glossy wet-look fabric and just the right amount of trouble.
