Forever 21 Size Chart: Official US/CA, UK, and EU Guide

Direct answer: Use Forever 21's official size chart as a body-measurement starting point, not as a promise that every item will fit the same way. The current guide gives women, plus, denim, bra, swim, and men's measurements, plus some UK and EU conversions, but cut and fabric still change the final fit.

How Forever 21 says to measure

The official size chart tells shoppers to measure the fullest part of the bust, the natural waist, and the fullest part of the hips. For bras, it also gives underbust guidance. That matters because this chart is a body measurement guide, not a garment measurement chart.

Women's apparel size chart

The current official chart lists these women's body measurements in inches:

Size	US/CA	Bust	Waist	Hips	UK	EU
XXS	00	31	22-23	31-32	2	30
XS	0	32	24-25	33-34	4	32
S	2/4	34-35	25-26	35-37	6/8	34/36
M	6/8	35-36	27-28	38-39	10/12	38/40
L	10/12	36-37	28-29	40-42	14/16	42/44
XL	14	38-41	30-32	43-45	18	46
XXL	16	42-45	33-35	46-48	20	48

The same official page also publishes centimeter equivalents if that is easier for you to use.

Women's denim chart

Forever 21's official denim guide uses waist-size denim numbers rather than alpha sizes:

Denim size	Waist (in)	Hips (in)	EU
24	24	34	32
25	25	35	32
26	26	36	34
27	27	37	34/36
28	28	38	36
29	29	39	38
30	30.5	40.5	38/40
31	32	42	40
32	33.5	43.5	40/42
33	35	45	44
34	36.5	46.5	46

Plus-size apparel and denim

The current official plus-size chart separates apparel and denim. Apparel uses 0X through 4X, while plus denim uses numeric sizes 12 through 22.

Plus apparel	Bust (in)	Waist (in)	Hips (in)	UK	EU
0X	42-43	36-37	46.5-47.5	18	46
1X	44-45	38-39	48.5-49.5	20	48
2X	46-47	40-41	50.5-51.5	22	50
3X	48-50	42-44	52.5-54.5	24	52
4X	51-53	45-47	55.5-57.5	26	54

Plus denim	Waist (in)	Hips (in)	Thigh (in)	UK	EU
12	35	46	26.5	18	46
14	37	48	27.5	18/20	46/48
16	39	50	28.5	20	48
18	41	52	29.5	22	50
20	43	54	30.5	24	50/52
22	46	57	32	26	52

Bras and swimwear

The official guide also covers bras, bralettes, and swimwear. Current bra sizing runs from 32A to 38C, with underbust and bust measurements plus an ASIA and UK conversion table on the same page. Swimwear is listed in S through XL and uses underbust, bust, waist, and hip measurements, which is more useful than relying on dress size alone.

Bra size	Underbust (in)	Bust (in)	ASIA and UK
32A	26-28	32-34	70B
32B	26-28	33-35	70C
32C	26-28	34-36	70D
34A	28-30	34-36	75B
34B	28-30	35-37	75C
34C	28-30	36-38	75D
34D	28-30	37-39
36B	30-32	37-39	80C
36C	30-32	38-40	80D
36D	30-32	39-41	80E
38C	32-34	39-41

Men's tops and bottoms

Forever 21 also publishes a men's size chart. Tops run from XS to XXXL, and bottoms can be read either by alpha size or waist number.

Men's tops	Chest (in)	Waist (in)	UK	EU
XS	36-37	28-29	34	44
S	38-39	30-31	36	46

How to use the UK and EU conversions safely

The official page does provide UK and EU conversions for women's apparel, plus apparel, plus denim, and men's tops, but not every category has every international equivalent. That means the safest method is to match your body measurements first and treat UK or EU labels as a secondary check. If the chart does not list a conversion for your exact category, do not guess one.

When the chart is not enough

Because the official guide is built around body measurements, it will not answer every fit question about rise, stretch, inseam, fabric recovery, or how oversized a style is meant to wear. Current product pages such as this Plus Size Denim Mini Dress show that item pages can surface the size chart directly, but that still points back to the general measurement guide rather than a full garment-spec sheet. If you are between sizes, fabric content and intended silhouette should decide the final call.

Bottom line

Forever 21's official size chart is useful and fairly broad, especially for women's apparel, denim, plus, bras, swim, and men's basics. Use it as a body-measurement reference, not as proof that every cut will fit the same, and avoid inventing conversions the official chart does not publish.
