ANATOMICAL MEASUREMENT
How to Take Your Measurements
Use a soft measuring tape. Stand tall, relax your shoulders, and breathe naturally. Keep the tape parallel to the floor without pulling tight against the skin.
1. Bust (Fullest point) · 2. Underbust Band
1. Natural Waist · 2. Full Hips · 3. Inseam
1. Bust · 2. Waist · 3. Hips · 4. Torso Loop
Bust
Measure around the fullest circumference of your bust. Keep the tape level across your shoulder blades at the back and comfortable across the front.
Underbust Band
Measure directly beneath your breasts along the ribcage where the supportive anatomical elastic band rests. Exhale normally for an authentic reading.
Natural Waist
Measure around the narrowest part of your waistline, typically located 2 to 3 cm above your belly button. Do not suck in your stomach.
Full Hips
Stand with feet together. Wrap the measuring tape around the fullest part of your hips and glutes, ensuring the tape remains completely horizontal.
Torso Loop (Girth)
Essential for the FA Teaser Onesie. Start tape at the highest point of your shoulder, thread down through the crotch, and return back up to the shoulder.
Inseam
Measure from the lowest point of the crotch seam straight down the inner leg to the ankle bone (7/8 legging) or mid-thigh (studio shorts).

Frequently Asked Sizing Questions
Because FA-WEAR utilizes high elastane recovery yarns, our pieces mold naturally to your contours. If you prioritize maximum core compression and locked-in support during athletic reformer Pilates, select your smaller size. If you prefer effortless comfort for everyday wear and gentle stretching, select the larger size.
Instead of removable foam inserts that bunch, wrinkle, or shift awkwardly after washing, our tops feature an anatomical double-layer underbust cradle. This structure gently lifts and contours naturally with your movements, delivering clean modesty and stability with zero bulk.
No. Our high-rise waistbands feature an ergonomic double-bonded top edge with an interior micro-grip weave. It stays flush against the lumbar spine and lower abdomen through pikes, short box series, and deep bends without digging in or slipping down.
All FA fabrics undergo pre-stabilization during milling. When washed cold on a gentle cycle and laid flat or hung to dry, your garments retain 100% of their original compression, color saturation, and recovery over hundreds of wears.
