This over sized mens' sweater was SUCH a bore, but is less than an hour it went from frumpy to totally FAB!

Here's how!

Cut off the arms.  Save them for other projects.  (You can use them to make a dog sweater!)

Remove the arms

Cut off the top of the sweater

Ok, so this next part is where things get a little tricky.  I used an XXL men's sweater.  Turns out that size is WAY too big for me.  Through a bunch of trial and error I ended up trimming the sweater down to a size that was just right.

The next time I make one of these (and I will make more) I'll start with a Medium or Large sweater.  That way I'll only have to add elastic and I'm all done!

Cut and sew to fit your body

 All you have to do now is add elastic.  (I'm not going to cover that part in detail because I'm assuming that you already know how to do it.)  

Turn down the top edge and add elastic.

PRO TIP:
My plus size sisters already know how annoying it is to make a cute dress or skirt only to have it be too short in the back.  I'm sure that this happens from time to time with all women, but as a big girl it happens to me A LOT!  I have come to call this annoying little problem Big Booty Ride Up.

Fixing Big Booty Ride Up

This problem is REALLY easy to fix!  Here's how:  Hem your skirt so that there is 3/4 -1 (or maybe even 2) inches of extra fabric at the back of the skirt.  You can adjust the elastic placement in the waist band to add an inch or 2 or you can make the adjustment at the hem of the skirt.  When laid flat the hem will look uneven.  When you wear the garment, the hem will be perfect!
