1) If you have a shorter neck, choose low scoop necks or v-neck tops. Avoid higher collars and turtlenecks.
2) For heavier upper arms, choose more tailored sleeves, dolman sleeves, and thick straps on your tank tops. Thicker straps will balance out your arms, thin straps will just exaggerate the size of your arms. Avoid cap sleeves.
3) Thick straps are also best of you have large breasts as are halter necklines that help `hoist`you up.
