No clue how busy Lithe is in regards to checking dA and/or replying here. But I can tell you a few things about her Medic cosplay at least.

The medigun was a more complicated build than I can summarize for. It's foam and I believe a bit of light weight wood and an ingenious construction allowing Lithe to take it apart for easier packing. She can screw off the barrel from the rest of it and even remove the top handle/lever by taking out a bolt.

The pack, however, was primarily foam core with some reinforced padding where it sits on the back. Again, more specific details would have to come from Lithe herself. I do seem to recall she had progress photos somewhere, perhaps.

For stuff like the gun and pack, if you want to go for a more accurate look, a big tip I can give is to make sure you proportion them properly. Use cheap paper (newsprint is great) to sketch out pieces and measure them against yourself to make sure they look right before you go cutting into your supplies.

She used a pattern for Neo's coat from the Matrix and altered it to make necessary changes for Medic's coat. Similar to above, you can use a cheaper fabric like muslin to test the pattern on and make sure your alterations will work and give you the effect you want before you go into sewing the final product.

She has a variety of gloves and I'm not sure what her most recent pair has been. I don't recommend painting dish gloves as it's very difficult to do without the paint cracking off. Most paints are not nearly flexible enough to adhere to latex rubber gloves and move and stretch with them without taking damage. If I recall correctly, all of the rubber gloves she's bought for Medic have been the result of some hardcore internet searching.

Trust me, though, this cosplay was all Lithe.

Oh no ;u;  But ahh hello hello!!  Thank you so much!  I do hope to come next year.  I had a BLAST being in the dating game!  I am on tumblr a lot so feel free to say hello or anything! 

Totally okay!  Thank you!
