I have a washable suede jacket from Eddie Bauer-- many years old and it is real suede vs faux. Time in the dryer is critical to the look. I never ironed it but i'd be concerned that a little too hot would mess up the fabric-- whether animal or synthetic.

Oh, now I also remember that I "air dried" it with one of those bumpy dryer balls to try and shake out the wrinkles, no heat. Also, I never put it in the dyer after I initially washed it, i hung it up to dry. The wrinkles were created by the agitation and spinning in the washer. The only heat I ever applied was trying to steam iron it, but after little success in a few spots I gave that up not wanting to set the existing wrinkles.

Make a pillow out of it!

Again-- the time in the dryer (with heat) is what removed the wrinkles in my washable suede jacket-- but i can't promise it is the same with all washable suede. (I don't even know how it can BE washable!)

Are you outside the window for returning the skirt?

Is it actual suede? The leather? Or a poly or micro suede of some sort?

When I worked at a biker gear company, they recommended using fabric softener for washing their motorcycle leathers.

Since you probably have nothing to lose at this point, I'd try another wash on extra delicate with fabric softener and hang dry, smoothing out the wrinkles by hand.

If you want try ironing out the wrinkles, do it on the backside using a damp pressing cloth.

Or FWIW, brown Kraft paper - a.k.a. grocery sack paper- can be dampened and used to press out wrinkles. I've done it with mixed success. It depends on the material. It also works to set creases.

I would put it in the dryer with a wet (not dripping, but definitely wet) towel, with heat, just until it heats up and is damp/steamed. Pull it out quickly and shake it...maybe 2 or 3 minutes is all that is needed, once the dryer heats up enough. If it seems to be working, keep putting it back until it looks like you want.

I've had it for decades. Guessing from how tight it is now, I'd say two ten lb. decades . . . didn't wear it much for past decade due to wrinkling and it getting too tight. If I can get it decent enough to donate I will. I'd save it for craft project but my house is literally overrun with craft supplies and saved junk. It is real leather.

Make it into a tote bag 😃
