What size should you choose for a Gertrude down jacket?
Introduction — Getting straight to the point (and avoiding returns)
Gertrude fits true to size (TTS) on the whole for down jackets & coats: a regular/fitted cut designed for everyday wear. The right size then depends on your body shape and what you want to wear underneath (a thin sweater vs. a thick hoodie).

Simple rules — how does Gertrude fit?

-
“Bright” models (Lilibright, OlgaBright, Vianneybright): clean/fitted look; TTS is a good starting point.
-
César sleeveless gilet: TTS; go for +1 if frequently worn over thick hoodies.

Measuring & trying on — the no-return method
Measuring
-
Chest: horizontal tape at the fullest point, breathing normally.
-
Waist: at the natural crease.
-
Hips (F): at the widest point.
Trying on
-
Put on your thickest layer (sweater/hoodie).
-
Zip closed: slip 1–2 fingers between your torso & the puffer.
-
Cross your arms: zero pulling at the shoulder blades.
-
Length: short = mobility; mid-thigh = protection.
-
Between two sizes: choose the larger one.
Care — keep the fluffiness & the shape
-
Wash 30°C delicate, mild detergent, no fabric softener.
-
Long rinse, light spin cycle.
-
Low-heat tumble dry with 2–3 balls (re-fluffs) or air dry flat while kneading the baffles.
-
If water no longer beads: reactivate water repellency (low heat for 10–15 min or DWR spray).
FAQ — Gertrude puffer sizing
Do Gertrude puffers run large?
They run true to size (TTS) with a regular/fitted look. Go up +1 if you often wear thick hoodies.
Are Lilibright & OlgaBright fitted?
They have a clean (feminine) silhouette. Stay TTS; go up +1 if you want a lightly oversized effect or if you layer a chunky knit.
Vianneybright for strong shoulders/biceps?
Yes, it’s the easiest for everyday wear: TTS, or even +1 if you like layering.
Is the César sleeveless vest actually warm?
It warms your core while leaving your arms free: ideal for mid-season and as an intermediate layer under a parka in winter.
Between two sizes, what should I choose?
For outerwear, take the larger one: you gain mobility and extend the lifespan of the seams (shoulders/biceps).
