Lyrics:

Stitch by stitch, stitching it together 
Deadline looms, don't you know the client's always right? 
Even if my fabric choice was perfect 
Got to get them all done by tonight 
Pinkie Pie, the color's too obtrusive 
Wait until you see it in the light 
I'm sewing them together! 

Hour by hour, one more change 
I'm sewing them together, take great pains 
Fluttershy, you're putting me in a bind 
Rainbow Dash, what is on your mind? 
Oh my gosh, there's simply not much time 
Don't forget, Applejack's duds must shine 
Dressmaking's easy, every customer's call 
Brings a whole new revision 
Have to pick up the pace, still hold to my vision 

All we ever want is indecision 
All we really like is what we know 
Gotta balance style with adherence 
Making sure we make a good appearance 
Even if you simply have to fudge it 
Make sure that it stays within our budget 
Got to overcome intimidation 
Remember, it's all in the presentation! 

Piece by piece, snip by snip 
Croup, dock, haunch, shoulders, hip 
Bolt by bolt, primmed and pressed 
Yard by yard, always stressed 
And that's the Art of the Dress!
