I just purchased my custom made insulin pump leg cuff from T&J Design
I haven't officially worn it yet, but after wearing it for a little while around my apartment, I'm very happy with it! It's so comfortable and doesn't slip at all. I'm planning on wearing it with a bridesmaid dress, so that will be the real test. I'm sure it will be fine though. I definitely recommend this company--they are very friendly and have great products! I found them through Karen's Bitter-Sweet Diabetes Blog---so thanks Karen!
