Oh, I didn't know you could adjust the days. (I'm new at this) Do you need this for a certain time/occasion? Let me know and I'll try to figure something out.
I'm pretty sure it would. When it lays flat it measures 16" across the front directly under the arm, and 14" across the waist (front only). It is very stretchy. The see through part is about 4 1/2" wide. I'm not sure if you could/would wear a bra with it. Hope this helps!
