Alright well maybe just a few things. Go ahead and give McCall's 5980 a whirl, if:
1. You like your jacket peplums to look like Judy Jetson's skirt
2. You enjoy buying the exact fabric the pattern calls for, only to have it produce a horrendous drape (or lack thereof)
3. You prefer to spend your evenings using crappy finishing techniques that clearly give your garment the not-so-coveted "home sewn" label
4. You like your sewing projects half-finished - particularly when it's so bad you gleefully throw it (and a good chunk of change) in the trash just to move on.
