Size guide


At Santan Gelos, we want to ensure you find the perfect fit across our entire range of nightwear, lingerie, and everyday apparel.

Because we partner with global designers and manufacturers, sizing may vary slightly depending on the style and fabric. Please use the sizing charts and measurement tips below as a general guide.

How to Measure Yourself

For the most accurate fit, measure yourself using a soft measuring tape while wearing light clothing or undergarments. Keep the tape straight and snug, but not pulled tight.

  • 1. Bust: Wrap the measuring tape around the fullest part of your bust, keeping the tape parallel to the floor.

  • 2. Underbust (for Bras & Lingerie): Measure directly around your ribcage, right underneath your bust line.

  • 3. Waist: Measure around the narrowest part of your natural waistline (usually just above your belly button).

  • 4. Hips: Stand with your feet together and measure around the fullest part of your hips and seat.

1. General Clothing & Nightwear (Dresses, Pyjamas, Tops & Loungewear)

If you fall between two sizes, we recommend sizing up for a more relaxed, comfortable fit.

Size EU UK US Bust (cm) Waist (cm) Hips (cm)
XS 32–34 4–6 0–2 80–84 60–64 86–90
S 36–38 8–10 4–6 85–89 65–69 91–95

XXL 48 20 16 109–115 89–95 115–121

2. Lingerie & Intimate Wear

Bralettes, Bodysuits & Panties

Due to the delicate nature and stretch of lace, mesh, and satin materials, intimate sets typically follow letter sizing:

Size EU Bottom / Dress Hip Measurement (cm) Fits Bra Cup (Guideline)
S 34–36 88–93 cm 70A, 70B, 75A
M 38 94–99 cm 75B, 75C, 80A
L 40–42 100–105 cm 80B, 80C, 85B
XL 44 106–112 cm 85C, 90B, 90C

Fit Tips & Sizing Advice

  • Non-Stretch Fabrics (Satin / Woven Silks): If a item has no stretch (like woven satin nightgowns or tailored dresses), we advise selecting one size up for optimal comfort and movement.

  • Stretch Fabrics (Ribbed Knits / Jersey / Elastic Lace): Choose your standard size for a figure-hugging fit.

  • Product-Specific Notes: Please check the individual product pages for specific garment lengths, fabric stretch details, or model height/size references.
