A fake Hermès Constance 18 is a replica of the small shoulder bag with the H clasp, roughly 18 cm across, 15 cm tall, and 5 cm deep. The good ones get three things right: proportion, leather temper, and the feel of the clasp. The bad ones fail in that same order, and the clasp usually gives them away before anything else does.
Start with size, not the logo
Constance sizing is unforgiving because the bag is small. On a replica, the flap often sits too flat, or the gusset is cut too wide so the bag bulges at the base when closed. Compare the flap height to the body height; on the 18 the flap covers a little more than a third of the front. Check the strap drop too. A strap that hangs long turns a shoulder bag into a crossbody bag, and that changes the whole look.
Leather and structure
Most replica Constance 18s are sold as Epsom or Togo. Epsom has a fine, even crosshatch grain and holds its shape. Togo is pebbled and softer. The tell is at the gusset and the flap fold: real calfskin creases and recovers, while coated split leather creases white and stays creased. I press a thumbnail into an inconspicuous spot and watch how fast it lifts back. Stiff is not the same as structured.
The H clasp is where replicas fall apart
Look at the gap between the H and the leather. It should be even on both sides. The plating should be mirror bright without orange peel, and the closure should have a defined snap rather than a mushy pull. Ask for a short video of the bag opening and closing. Photos hide a loose hinge better than anything else.
Stamps and hardware markings
Blind stamps on replicas are usually too deep or set in the wrong place, and the lettering looks stamped rather than pressed. Hardware engravings are often too dark. Under raking light, the edges of the H should look polished, not filed.
Stitching, edge paint, interior
Stitch length should be consistent and the angle should lean the same way along a seam. Edge paint on a cheap bag is thick, bubbly, or already cracking at the corners. Inside, the Constance 18 is simple: a flat leather interior with a slip pocket. Fabric lining is an immediate no.
Price tiers and red flags
- Entry tier, roughly $150 to $300: machine stitched, stiff leather, weak plating.
- Mid tier, roughly $350 to $600: better leather and clasp, uneven edge paint.
- Top tier, $700 and up: hand-finished edges, correct hardware weight, real calfskin.
Anyone promising full hand stitching at $200 is not telling you the truth. Sellers who only show factory stock images, refuse a clasp video, or dodge questions about leather type are the ones to skip. Wear points tell the rest: corners, strap folds, and the flap edge after a month of use.
