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.

A Sure Thing became a customer favourite for a reason.

This curvy black lace bodice set combines softer stretch lace with a little more structure and shaping through the torso, creating a style that feels flattering, wearable, and surprisingly comfortable to move in. The lace-up satin front allows for extra adjustment through the bust and waist, while the garter details give you the option to style it with stockings for a more complete lingerie look.

It sits somewhere beautifully between a softer bodysuit and a more structured basque — making it a popular choice for customers wanting support and shape without feeling heavily restricted.

If you’re unsure whether a bodysuit, basque, or contour style suits you best, you may find these guides useful:

Key Features:

  • Soft stretch black lace that feels flexible and comfortable against the body
  • Lace-up satin front allows for a more adjustable and flattering fit
  • Structured bodice design offers shape and support without feeling overly restrictive
  • Cheeky open crotch G-String for and added surprise
  • Four removable garter straps allow you to pair with stockings for a more styled look
  • Wire-free support (S–L) with added underbust structure in curvy sizing (XL–3XL)

Ideal for customers wanting a little more structure, shaping, and support while still feeling comfortable, flattering, and easy to wear.
