How to measure

Use a soft measuring tape. Keep it snug, not tight.

Bust Measure around the fullest part of your bust, tape parallel to the floor.

Underbust Measure directly under your bust where a bra band sits.

Waist Measure the narrowest point (usually above the belly button).

Hip Measure around the fullest part of your hips/seat.

Inseam (jeans/leggings) Measure from the top of the inner thigh down to your ankle.

Tip: If you’re between sizes, choose based on comfort preference: more smoothing = size down, more comfort = size up.

Shapewear

High-compression items: choose your true size for best smoothing.

Spants Size	US Dress	Waist (in)	Hip (in)
XS	0–2	24–26	34–36
S	4–6	27–29	37–39
M	8–10	30–32	40–42
L	12–14	33–35	43–45
XL	16–18	36–39	46–49
1X	18–20	40–43	50–53
2X	20–22	44–47	54–57
3X	22–24	48–51	58–61

If your waist and hip fall into different sizes, choose based on the area you want the most smoothing.

Bodysuits

Best fit depends on bust + torso length. If long torso, consider sizing up.

Spants Size	Bust (in)	Waist (in)	Hip (in)
XS	31–33	24–26	34–36
S	34–36	27–29	37–39
M	37–39	30–32	40–42
L	40–43	33–35	43–45
XL	44–47	36–39	46–49

Bras

Use underbust for band and bust for cup. This chart is a simplified guide.

Underbust (in)	Suggested Band	Bust difference*	Suggested Cup
27–28	30	1" / 2" / 3" / 4"	A / B / C / D
29–30	32	1" / 2" / 3" / 4"	A / B / C / D
31–32	34	1" / 2" / 3" / 4"	A / B / C / D
33–34	36	1" / 2" / 3" / 4"	A / B / C / D
35–36	38	1" / 2" / 3" / 4"	A / B / C / D

*Bust difference = (full bust) – (underbust). Example: 36 bust – 32 underbust = 4" → D cup.

Underwear

Choose based on hip for the most comfortable fit.

Spants Size	Hip (in)
XS	34–36
S	37–39
M	40–42
L	43–45
XL	46–49

FAQ

Quick answers about fit and sizing.

I’m between sizes — what should I do?

If you want more smoothing/compression, size down. If you want a softer everyday feel, size up.

Will shapewear feel tight?

Shapewear is designed to compress. If you prefer less compression, choose your larger size or select a lighter-support style.

Do you have help if I’m still unsure?

Yes — contact support with your bust/waist/hip measurements and what you’re buying. We’ll recommend the best starting size.
