Size guide
UK 6–18 body measurements, ring sizes, belt ranges, and exactly where we measure.
All apparel is cut to UK sizing. The tables below are body measurements, not garment measurements — measure yourself and pick the row you land in.
Apparel — UK 6 to 18
| UK size | Bust | Waist | Hip |
|---|---|---|---|
| UK 6 | 78–80 cm | 60–62 cm | 86–88 cm |
| UK 8 | 82–84 cm | 64–66 cm | 90–92 cm |
| UK 10 | 86–88 cm | 68–70 cm | 94–96 cm |
| UK 12 | 91–93 cm | 73–75 cm | 99–101 cm |
| UK 14 | 96–98 cm | 78–80 cm | 104–106 cm |
| UK 16 | 101–104 cm | 84–87 cm | 109–112 cm |
| UK 18 | 107–110 cm | 90–93 cm | 115–118 cm |
Where we measure
- Bust — around the fullest part, tape level all the way round, arms down.
- Waist — the narrowest part of the torso, usually just above the navel. Do not pull the tape tight.
- Hip — around the fullest part of the seat, roughly 20 cm below the waist.
How each group fits
- Fitted shirts — cut close through the rib and waist with bust darts. If you are between sizes and intend to tuck the shirt in, take the larger size.
- Bodysuits — heavier stretch jersey, cut to be snug. Take your usual size; they are not sized down.
- Pencil mini skirts — sized on the waist, not the hip. Faux leather (PU) styles are fully lined and have no give, so if your hip measurement is at the top of a row, take the next size up.
- Tailored shorts — sized on the waist. Polyester twill styles have no stretch; the cotton-elastane styles have a little recovery through the hip.
Ring sizes
| UK size | Inside circumference | Inside diameter |
|---|---|---|
| UK J | 48.7 mm | 15.5 mm |
| UK L | 51.2 mm | 16.3 mm |
| UK N | 53.8 mm | 17.1 mm |
| UK P | 56.3 mm | 17.9 mm |
| UK R | 58.9 mm | 18.8 mm |
To measure: wrap a strip of paper round the base of the finger, mark where it meets, and measure the length in millimetres. That is your inside circumference. Wide-faced rings sit tighter than narrow bands, so if you are between rows take the larger.
Belts and ear cuffs
Wide belts are punched with five holes and the adjustable range is printed on each product page — most run 70 to 105 cm. Chain belts adjust with an extender chain; the range is on the page. Measure over the clothes you intend to wear the belt with, not against bare skin.
Ear cuffs are one size. They are a sprung band that grips the outer cartilage and they need no piercing; squeeze the band gently to tighten the grip, or open it slightly if it feels tight. Each cuff is sold singly, so order two if you want a pair.
Still unsure
Send your bust, waist and hip measurements and the style you are looking at to support@aivelo.shop and we will tell you which size we would send. If it turns out wrong, the returns policy covers it.
