look at the bias dress hem center back. this is before....... hem was 8" or more longer in back than the sides and front.
This is the dress I wove in april on my saori loom and sewed. The bias hem just kept "growing" and was 6"or more longer in the back! So I re hemmed it and cut off quite a bit enough for some unusual pockets .I like it much better now with pockets, room for my cell phone, keys and other things and to wear over leggings.
