The Gymshark Vital Seamless is everywhere. TikTok, Instagram, your gym. But does it actually work for curvier bodies — or is it only flattering on the influencers with straight hips?
We pulled real reviews from the Forre community. Here's what women with curves actually found.
What is the Gymshark Vital Seamless?
The Vital Seamless is a two-piece set (leggings + sports bra) in a marl-effect seamless fabric. It's designed for low-impact activity — yoga, Pilates, casual gym. The main appeal is the snatched aesthetic: ribbed panels that create the illusion of a defined waist.
Does the Vital Seamless work for curves?
The honest answer: it depends on where your curves are.
For hourglass shapes (balanced bust + hips, defined waist)
This is the best-case body type for the Vital Seamless. The waist panelling actually flatters rather than flattens, and the hip coverage is generous enough that most hourglass women find it comfortable.
Community consensus: size up one if you're between sizes. The fabric is thick but has limited stretch — going too small means the waist panel digs in.
For pear shapes (narrower shoulders, wider hips and thighs)
More mixed. The leggings are the best part — the thigh coverage is solid and the ribbing sits flat even on wider thighs (UK 14–18).
The sports bra is a problem. Gymshark sizes the Vital Seamless bra for smaller busts. If you're a D cup or above, the bra offers minimal support and the band digs in under the bust if you size up for cup coverage.
Recommendation for pear shapes: Buy the leggings in your regular size. Skip the matching bra unless you're an A–C cup.
For plus sizes (UK 16+)
Gymshark has extended the Vital Seamless to a 3XL (roughly UK 22–24). The quality and stretch hold up well at larger sizes according to our community.
The waist panel does compress — some women love this, others find it uncomfortable for longer sessions. One reviewer noted: "It holds everything in which looks great in the mirror but after an hour of Pilates I needed to sit down just to breathe."

The Forre verdict
Buy if: You're hourglass or pear-shaped below a D cup, primarily doing low-impact training.
Skip if: You need proper bust support, or you're doing anything more intense than yoga/Pilates.
