Ask the Laundress
I recently bought a black dress in a stretch heavy gabardine wool type fabric and I need the collars on the top to stand upright, otherwise the dress looks frumpy! Can I use starch to do this without ruining the garment?
You can definitely try starch, but I don't know if it will work well since the fabric is heavier than the standard cotton shirt.
You may consider having your tailor or local cleaner put collar stays in the collar for you.
