I used to bring a portable steamer. Then they came out with Downy Wrinkle Release. That stuff is wonderful! I use it daily, and my husband now uses it instead of wasting time ironing each morning. You just spray it on, pull the fabric and smooth out the wrinkles. It might not work well on really bad wrinkled stuff, or deep wrinkles, but for every day stuff its great. You can find it in the laundry aisle in most stores. It comes in an ivory colored spray bottle and can be tough to find in the sea of products.
