Alcima US Size Chart

Alcima US Size Chart

Find Your Alcima Fit

Our size chart is based on body measurements in inches. For the best fit, measure your bust, natural waist, and fullest hip using a soft measuring tape. For leggings and bottoms, choose your size based primarily on hip measurement. For bras and tops, choose primarily on your bust measurement. If you are between sizes, size down for a more compressive, second-skin feel, or size up for a more relaxed fit.

All measurements are body measurements in inches. If you fall between sizes, choose the smaller size for a closer, sculpting fit or the larger size for a more relaxed fit.

Alcima Size US Numeric Size Bust Waist Hip
XS 0–2 32–34 in 24–26 in 34–36 in
S 4–6 34–36 in 26–28 in 36–38 in
M 8–10 36–38 in 28–30 in 38–40 in
L 12–14 38–41 in 30–33 in 40–43 in
XL 16–18 41–44 in 33–36 in 43–46 in

This range sits in line with common U.S. women’s apparel sizing while maintaining measurements appropriate for fitted activewear.

Leggings and Bottoms

For leggings, shorts, skorts, and flares, use your waist and hip measurement as the primary guide.

Alcima Size US Numeric Size Waist Hip Suggested Full-Length Inseam*
XS 0–2 24–26 in 34–36 in 27–28 in
S 4–6 26–28 in 36–38 in 27–28 in
M 8–10 28–30 in 38–40 in 27–28 in
L 12–14 30–33 in 40–43 in 27–28 in
XL 16–18 33–36 in 43–46 in 27–28 in

Nova Collection: Please keep in mind the Nova collection runs small, so you should size up.

Fit note for bottoms: If your waist and hip measurements fall in different size ranges, choose the size that matches your hip measurement for the most comfortable fit through the seat and thighs. This is a common activewear recommendation because hip fit is usually the limiting dimension in leggings and fitted bottoms.

Sports Bras and Tops

For bras, tanks, long sleeves, and fitted jackets, use your bust measurement as the primary guide.

Alcima Size US Numeric Size Bust Waist
XS 0–2 32–34 in 24–26 in
S 4–6 34–36 in 26–28 in
M 8–10 36–38 in 28–30 in
L 12–14 38–41 in 30–33 in
XL 16–18 41–44 in 33–36 in

Fit note for tops: For compression bras or high-support styles, sizing up is recommended for more comfort. For light-support bras and stretch tanks, you can generally choose your usual Alcima size. Please keep in mind Nova collection runs small.

How to Measure

Use a soft measuring tape and wear fitted clothing or undergarments. Keep the tape level with the floor, comfortably snug, and not pulled tight.

1.

Bust: Measure around the fullest part of your bust, with the tape passing under your arms and across your shoulder blades.

2.

Waist: Measure around the narrowest part of your torso—usually just above the belly button. Bend gently to one side to find your natural waist crease.

3.

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

4.

Inseam: Measure from the top of your inner thigh/crotch seam to the point where you want the hem to fall. You can also lay a favorite pair of leggings flat and measure along the inner leg seam.
