All Dressed Up - This is an interesting costume site. They rent costume and sell them as well. Plus they have a makeup page with some photos of what they can provide. Not as good as some others I have seen but OK. Have a look.

Fashion Links - This is a great site for links related to costumes, costumer builders, designers and anything related to fashion. Plus some links relating to special effects makeup but mostly costuming and fashion. Most complete I've seen yet. Check it out for sure.

Star Design Costumes - This is a full and complete costume site that not only deals in costumes but has a full range of things for our uses. They have everything from body part props to makeup supplies and accessories of all kinds. Their prices are quite reasonable as well for most all of their items. Check this one out.
