Both are elegant and comfort will depend on the style and fit of the dress. In many casesas well, the style of the dress will dictate which fabric should be used. Your best bet is to look at some off the rack dresses for ideas. Are you planning to have these dresses made or buy ready made ones? If you are buying ready made dresses, then get some ideas by looking in the shops. It would be difficult to tell which fabric you prefer by just looking in magazines. Also, you could visit a fabric shop and they would be only too happy to show you bolts of both fabric and you may be able to tell by touching them, which you prefer. Good luck.
