Alma BB: real vs fake
The Alma BB is the scaled-down version of a 1934 silhouette: a rigid, structured body with a domed top that is genuinely hard to manufacture. That dome geometry and the double zipper are exactly what replicas reproduce worst.
What to check on the Alma BB
Model-specific zones — on top of the brand-level signs.
Dome geometry
The body is rigid, the top arc is smooth and symmetrical on both sides, and the bag stands upright without tipping. Replica domes often look crumpled, with an uneven arc or flat spots.
Double zipper
Two house-branded zippers meet at the top center of the arc and glide smoothly through the entire curve. Snagging on the bend and unmarked sliders are classic fake tells.
Clochette, lock, and keys
The bag comes with a leather clochette, keys, and a padlock: the number on the lock matches the keys, and the engraving is deep. A missing set isn’t fatal for a pre-owned bag, but mismatched numbers are a red flag.
Toron handles
Short rolled toron handles with neat glazing and symmetrical anchors. On the Monogram version the vachetta develops natural patina, with even stitching on the anchor tabs.
Detachable shoulder strap
The Alma BB is worn crossbody: strap clasps are house-branded, weighty, with clean engraving; the strap edges are glazed to match the body trim.

FAQ
My Alma BB came without the lock and keys — is it fake?
Not necessarily: pre-owned bags often lose the set. But if the lock and keys are present, their stamped numbers must match and the engraving must be deep and even. A “brand new” bag from a seller with no set is a reason to be cautious.
Should the zipper run one-handed through the whole arc?
Yes — on an authentic bag both zippers glide smoothly around the entire dome without catching. A zipper you have to drag through the curve is a common sign of a replica with cheap hardware.
