While I haven't worn these items often, they have been stored at home (in a dark closet) for a long time. They were all kept in dust covers, so I think there is little damage. The short-sleeved check shirts are made of seersucker fabric (two shirts). The other one was purchased in Hawaii and worn almost exclusively at that time. The long-sleeved striped shirt has lining and is slightly thicker. The sweater has never been worn. As you can see from the tags, almost everything is Eddie Bauer, except for the Hawaiian fabric shirt and the sweater. Eddie Bauer is an American size, so Size S is equivalent to size M in Japan. I think these are recommended for those who want to throw something on over a T-shirt, etc., or for those who want a variety of items. They have been washed at home, and there may be some residual scent of fabric softener. I think it would be best to wash them again at home before wearing them. Size...M
