Peace Out Women's Costume

I normally would wear a medium shirt and pants size 8-10. I purchased a medium size costume. The costume shirt is stretchy but it is small and short. Will make it work because I don't want to spend additional money on a top. Vest is small and tight without stretch. Cut shoulder seams and side seams under arms. Then used fabric tape and ironed cut pieces of the headband to the shoulder and side seems to widen the vest and open up arm holes. A glue gun would probably work too. Pants are very cute but very hot unfortunately. Pants are almost too big but ok. I'm thick wasted and still might have to use safety pins on the waist of the pants to prevent having to pull up on them all day. Overall it's a cute looking outfit but it's certainly a size mismatch between the tiny size of the shirt and vest compared with the slightly oversized pants. Cheaply made but that's common for costumes and should be expected.
