The advantage of the fabric we use in our suits, is that it doesn't crease that quickly. However, when some creases have appeared after wearing it, there are a couple of things you could do.
You can try hanging up your suit in the bathroom for at least 15 minutes after you have turned on the shower at a high temperature. The steam should help getting rid of some of the wrinkles.
Our suits may be ironed carefully, but please make sure you iron at the lowest possible temperature.
You can always take your suit to your local dry cleaner. If the bathroom isn't doing the trick for you and you don't feel like ironing (who does...) we recommend taking your suit to a dry cleaner.
