Size Guide

Our pieces are designed to fit Australian sizing. Grab a soft tape measure and take two minutes — getting your size right first time means less fuss and no return trips to the post office.

How to measure

1
Underbust (band)Measure snugly around your ribcage, directly under your bust. Keep the tape level and firm — this sets your band size (8–16).
2
Bust (cup)Measure around the fullest part of your bust, tape relaxed and level. The difference between this and your underbust sets your cup (B–E).
3
Waist & hips (for bottoms)Waist: around the narrowest part. Hips: around the fullest part of your seat. These set your S–2XL for G-strings & suspenders.

Bra sizing

Step 1 — find your band from your underbust measurement:

Underbust (cm) 63–67 68–72 73–77 78–82 83–87
Band size 8 10 12 14 16

Step 2 — find your cup from the difference between your bust and underbust:

Bust − underbust (cm) 14–16 16–19 19–21 21–24 24–26
Cup B C D DD E

Put them together for your size — e.g. underbust 70 cm + a 17 cm difference = 10C. Available 8B–16E.

On the line between two sizes? For the band, size down for a more supportive fit (the band should feel snug, not tight). For the cup, size up for fuller coverage.

G-strings & suspenders

Size AU dress Waist (cm) Hip (cm)
S 8–10 64–72 89–97
M 10–12 72–80 97–105
L 12–14 80–88 105–113
XL 14–16 88–96 113–121
2XL 16–18 96–104 121–129

Our mesh and lace have gentle stretch, so they're forgiving across the range. If you're between sizes, size up for comfort.

Fit tips

  • Wear your best-fitting bra to compare. If a current bra fits you perfectly, match its band and cup as a starting point.
  • The band does the work. Around 80% of support comes from the band — it should sit level and snug around your body, not ride up at the back.
  • Straps are a fine-tune, not the lift. Adjust them so two fingers slide underneath comfortably.
  • Measure in an unpadded bra (or none) for the truest numbers.
