I'm super lame I know, but I made Hades a coat, it's really inexpensive if you have a sewing machine, and for a vest I imagine you could just sew it by hand it wouldn't take long at all.
Hades had a winter coat so it required a lot of stitching for the stuffing.
If there's a fabric land nearby just get a meter of fabric. Orange is good for a working dog! LOL, I imagine a meter or two wouldn't be more than $10-$15.
A meter of velcro or buckles. The heavy duty velcro is about $5/m, the buckles are really expensive like $5 each!
Cut out the pattern, the two lips that come around to the chest, and the part for the body. I measured from the neck to the tail, and from the shoulder to the middle of the chest, took 2 inches off the shoulder to chest (you'll have velcro for that part and put some velcro/buckle in the girth, you could put two but the vest would be light and you the back buckle sometimes rubs against... well you know! LMAO
Buy some iron on letters, about 50 cents each and there you go!!!!
I know I'm super lame, but Hades needed a winter coat and the ones at the pet store were too gay, can you imagine Hades in leopard print! LMAO, he's already a puss!! haha, so seeing as his colours camo he got a camo coat that he puked on and I had to throw out... yeah TMI... LMAO
