STRVNG Size Guide

STRVNG Size Guide

Designed for studio-to-street performance with a second-skin feel. Use the UK-centric chart below, then toggle units if you prefer inches. For a sculpted look, choose your usual size; for a relaxed feel, consider one size up.

Tip: Measure in underwear or light layers, standing tall with feet together.

Use your body measurements, not clothing measurements. Values reflect intended fit ranges for STRVNG stretch fabrics.

Sports Bras & Support Tops

Underbust (cm / in)

Measure snugly around the ribcage, directly under the bust.

Underbust Recommended Band Alpha Size Support
68–73 cm 30–32 XS Light–Medium
73–78 cm 32–34 S Medium
78–83 cm 34–36 M Medium–High
83–88 cm 36–38 L High
88–93 cm 38–40 XL High

Cup volume scales with alpha size in STRVNG styles. For fuller cups, size up the alpha (e.g., S → M) for comfort.

Compression Guide

  • Sculpt (High Compression): max hold for runs & HIIT — may feel firm on first wear.
  • Train (Medium): balanced hold for daily training & Pilates.
  • Flow (Light): soft stretch for yoga, recovery, and layering.
Between sizes? Prefer sculpted? stay true to size. Prefer comfort? size up.

How to Measure

  1. Bust: Tape around the fullest part, arms relaxed.
  2. Waist: Natural waist (just above navel), do not suck in.
  3. Hips: Widest point of seat, feet together.
  4. Inside Leg: Top of inner thigh to ankle bone.

Measure close to skin, not tight. If measurements span two sizes, your fit preference and fabric compression should guide you.

How It Should Feel

  • Second-skin: close to body, no pinching; seams lay flat.
  • No sheen test: if fabric shines when static, you may need one size up.
  • Break-in: compression softens slightly after 1–2 wears.
Model reference: Add per-product notes (e.g., “Model 172 cm, UK 8, wears S – true to size, medium compression.”)

Product-Specific Notes

Leggings

  • Flow / Flared: true to size; size down only if you prefer a locked-in feel at waist.

Tops & Jackets

  • Second-skin tees: true to size.
  • Zip tops with built-in bra: choose by bust; size up for broader shoulders.
  • Layering pieces: true to size for a sleek line; size up for relaxed drape.
