So I've done some testing. I'm 2XL and probably 5'2. I tried the Rip Skirt and the original and knee-length Macabis.
Rip Skirt: I got one in length 3 (knee length) - on me, it hits mid-calf. It has 2 hip pockets that will hold my iphone mini, but they are not quite deep enough. The skirt has some pleating, and honestly, it looks formal enough that I could (and have) worn it out for a nice dinner. It's pretty stain-resistant, though when my cats track cat litter on it, I can't just sweep it off as I do with the Macabi - I have to actually apply water. It does dry pretty fast (though not as fast as the Macabi). I will probably get a length 2 and see if it's more the length I want, but this one won't be my everyday Camino skirt.
I got knee-length Macabi skirts in XL and XXL. Both fit. I have more pocket real-estate with the XXL, naturally. Oh my gosh, these are homely - both the waist and the way they hang.
I got the original in XXL - XXL only comes in regular length. I trip over it
. But once it goes to the seamstress, I think it will be the Skirt. I am in love with the pockets, especially that zip pocket. I can fit an iPod mini in either of the hip pockets. The pockets on the knee-length look the same size but won't fit an ipod (and the phone cozy won't fit my iphone). I think the waist looks better, and the hang is much better. Nobody is going to think I'm wearing a fitted skirt and I'm okay with that. Add a belt and the waist appearance is much improved. Okay, I wish it was more fashionable, a girl can wish.
I've trained in the Rip Skirt in the fall and the knee-length Macabis this winter with leggings or slip shorts underneath. I like having my slip shorts or legging be separate from the skirt. Once I get the original hemmed up, I look forward to hitting the streets in it.
Hope this helps anyone who's thinking about wearing a skirt on the Camino.
