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.
