Bras & Bralettes

Bra Size Guide

Linsori bras follow UK band-and-cup sizing. The main collection covers bands 30–42 with cups A–G. Use the band chart to find your underbust size, then the cup chart to find your cup.

Band Size (Underbust)

Underbust (cm)	UK	US	EU	FR	IT	AU
63–67	30	30	65	80	0	8
68–72	32	32	70	85	1	10
73–77	34	34	75	90	2	12
78–82	36	36	80	95	3	14
83–87	38	38	85	100	4	16
88–92	40	40	90	105	5	18
93–97	42	42	95	110	6	20

Cup Size (Bust minus Underbust)

Difference (cm)	UK	EU	US	FR / IT
10–12	A	A	A	A
12–14	B	B	B	B
14–16	C	C	C	C
16–18	D	D	D	D

22–24	F	G	G	G
24–26	FF	H	H	H
26–28	G	I	I / J	I

Bralettes & Soft Cup Bras. Many soft-cup pieces are sized S/M/L instead of band-and-cup. As a guide: S/M fits UK 32A–34C, L/XL fits UK 34D–36DD, 2XL/3XL fits UK 38DD–40E. Always check the size dropdown on the product page for confirmed availability.

Lingerie

Lingerie Size Guide

For chemises, babydolls, bodysuits, teddies, corsets, and lingerie sets.

Size	UK	US	EU	FR/IT	Bust (cm)	Waist (cm)	Hips (cm)
S	8–10	4–6	34–36	36–38	81–87	61–68	85–92
M	10–12	6–8	36–38	38–40	87–93	68–74	92–98
L	12–14	8–10	38–40	40–42	93–99	74–80	98–104
XL	14–16	10–12	40–42	42–44	99–105	80–86	104–110
2XL	16–18	12–14	42–44	44–46	105–113	86–94	110–117
3XL	18–20	14–16	44–46	46–48	113–120	94–102	117–124

Between two sizes? For fitted pieces — bodysuits, corsets, sets — size up for comfort and structure. For drape pieces like chemises and babydolls, your usual size is right.

Panties

Panties & Briefs Size Guide

For thongs, briefs, hipsters, high-waisted briefs, and shapewear briefs.

Size	UK Dress	US	EU	FR	Waist (cm)	Hips (cm)
XS	6–8	2	34	36	58–64	83–88
S	8–10	4	36	38	64–70	88–94
M	10–12	6	38	40	70–76	94–100
L	12–14	8	40	42	76–82	100–106
XL	14–16	10	42	44	82–88	106–112
2XL	16–18	12	44	46	88–95	112–119
3XL	18–20	14	46	48	95–102	119–126

Shapewear briefs & girdles. Shapewear is designed to compress and sculpt, so it will feel firmer than standard panties — this is intentional. Choose your true size based on hip measurement. For stronger control, choose a piece with a higher control level rather than sizing down.

Sleepwear

Sleepwear Size Guide

For nightgowns, robes, kimonos, pyjamas, and loungewear.

Size	UK	US	EU	FR	Bust (cm)	Waist (cm)	Hips (cm)
S	8–10	4–6	34–36	36–38	81–87	62–68	86–93
M	10–12	6–8	36–38	38–40	87–93	68–74	93–99
L	12–14	8–10	38–40	40–42	93–99	74–80	99–105
XL	14–16	10–12	40–42	42–44	99–105	80–86	105–111
2XL	16–18	12–14	42–44	44–46	105–113	86–94	111–118
3XL	18–20	14–16	44–46	46–48	113–120	94–102	118–125

Robes & kimonos. These are designed for a relaxed, wrap-around fit. Stay with your usual size — sizing up is rarely needed.

Swimwear

Swimwear Size Guide

For one-pieces, bikinis, and beachwear.

Size	UK	US	EU	Bust (cm)	Waist (cm)	Hips (cm)
XS	6–8	2–4	32–34	78–83	58–64	83–89
S	8–10	4–6	34–36	83–88	64–70	89–95
M	10–12	6–8	36–38	88–94	70–76	95–101
L	12–14	8–10	38–40	94–100	76–82	101–107
XL	14–16	10–12	40–42	100–106	82–88	107–113

Swimwear fit. Swimwear stretches when wet. For a snug, supportive fit out of the water, choose your true size. Sizing up tends to leave the piece loose and saggy after the first swim.

Stockings, Hold-Ups & Tights

Hosiery Size Guide

Unlike clothing, hosiery is sized by height combined with hip or thigh measurement. Both matter — choose the row your hip or thigh falls into, then check your height column.

Tights & Stockings (Hip + Height)

Hip (cm)	Height 150–165 cm	Height 165–175 cm	Height 175–182 cm
86–96	S/M	S/M	M/L
96–104	M/L	M/L	L
104–112	L	L/XL	L/XL
112–120	XL	XL	XL
120+ (Plus)	XXL+	XXL+	XXL+

Hold-Ups & Stockings (Thigh + Leg Length)

Size	Thigh Circumference (cm)	Leg Length (cm)
S/M	50–55	69–74
L/XL	55–60	74–79
XL+	60–67	79–84
XXL+	67–75	84+

Between sizes? For hold-ups, choose by thigh — a too-tight band slips down. For tights, choose by hip when your waist and hip don't match the same size.

Plus Size

Plus Size at Linsori

Almost half of the Linsori collection is offered in plus sizes. The plus size threshold sits at:

Category	Plus Size Threshold
Clothing & Lingerie	UK 16 (XL) and above
Bras (band)	UK 38 and above
Bras (cup)	UK E and above
Panties & Briefs	UK 16 (XL) and above
Hosiery	Hip 120 cm+ (XXL+)

Plus size pieces are listed as their own product. Sizes range from XL to 3XL (UK 14 to 22) across most pieces, with a select extended range reaching UK 28 (6X) on certain plus collections.

Plus size is graded, not scaled. Each plus size piece is designed with proportional cups, extended bands, and wider hip room — not simply stretched from a standard size. If you usually wear UK 16, start with XL.

How to Measure

For the most accurate fit, measure in your underwear with a soft tape. Stand naturally and breathe normally — don't hold your breath in. All measurements are taken at the fullest or narrowest point as noted.

Bust

Wrap the tape around the fullest part of your bust. Keep it level and parallel to the floor. Do not pull tight.

Underbust

Measure directly under your bust, where a bra band sits. Keep the tape snug and level around your ribcage.

Waist

Measure around the narrowest part of your natural waistline — usually just above the belly button.

Hips

Stand with feet together. Measure around the fullest part of your hips and seat, about 20 cm below your waist.
