Ok, since I'm really short (like 4' 11 1/2") all pants are hugely long on me. Now I know the solution to that is hemming my pants, BUT what about the wonderful crotch area. I like to wear my pants low and I'm REALLY addicted to Modrobes (and the similar). I have a few pairs and my problem is the crotch sits at my mid thigh and it's getting annoying to look like I have this hugely long crotch area. Does anyone know how I would go about making the waist area smaller? Does that even make sense? I was thinking about pulling apart a pair I wasn't too concerned about and testing out the shortening of the mid-section, but I figured that asked the talented folks here would be the answer! I hope someone can help out!

Sorry this is text only. I havn't been too crafty lately since I've just gone back to school! One day I'll post some of the crafts.
