The one measurement that most folks find crucial is arm opening. Perhaps make a note circumference beginning underarm up over shoulder back down, then again thickest part of your arm to fit comfortably in desired sleeve length. Necklines is totally a personal preference and I’m pretty sure you know what you like so be sure and tell me. Look I’m visual too feel free to drawn on my girl and message me a phone photo, perhaps give her a tattoo or whatever, I’m good with all that.
