How to Measure

Band SizeMeasure around your ribcage, directly under your bust. Keep the tape snug but comfortable. Round to the nearest even number.

Bust MeasurementMeasure around the fullest part of your bust, keeping the tape parallel to the ground. Do not pull tight.

Calculate Cup SizeSubtract your band measurement from your bust measurement. Each inch difference = one cup size (1"=A, 2"=B, 3"=C, etc.).

TipsMeasure with a soft tape over a non-padded bra. Stand straight and breathe naturally for accurate results.

How to Measure

HipsMeasure around the fullest part of your hips and bottom, usually about 7–9 inches below your waist. Stand with feet together.

TipsKeep the tape snug but not tight. Wear minimal clothing. Take measurements while standing relaxed.

Bodysuit Fit Notes

Bodysuits are designed with 4-way stretch for a comfortable, second-skin fit. We recommend choosing based on your bust measurement first. If you are between sizes, size up for a more relaxed fit. The gusset snap closure allows for easy on and off — simply measure your torso length from shoulder to crotch for the best fit.

Sizing FAQ

What if I'm between sizes? +

If you fall between two sizes, we generally recommend sizing up for robes and slips, and sizing down for bralettes to ensure a snug, supportive fit. When in doubt, consult our size calculator above or contact our fit specialists.

Do Séraphine pieces stretch? +

Most of our lace and mesh pieces contain elastane and will have some stretch. Our silk and satin pieces have minimal stretch. Size charts are based on relaxed garment measurements — always compare to your body measurements.

How do I know if a bra fits correctly? +

A correctly fitted bra should: lie flat against your sternum, have cups that contain all breast tissue without spillage, have straps that don't dig in or slip, and have a band that sits level around your body. The band provides 80% of support.

Can I return if the size doesn't fit? +

Absolutely. We offer free returns within 30 days for unworn items with tags attached. Visit our returns portal or contact us to initiate a return or exchange.

Are sizes consistent across collections? +

Sizing can vary slightly between collections due to different styles and materials. We always recommend checking the specific size guide on each product page and measuring yourself before ordering.
