^^^ Great suggestions, Sammy and Tomato4....I was just about to post the same exact tips! I've found that any kind of sleeveless shirt that goes right to the tip of my shoulders makes my upper arms look like a dude's. And small armholes on sleeveless tops squeeze my fleshy upper arms and totally call attention to them. Yuck!
I've found success with short-sleeved puff sleeve cotton tops...the "puff" part is very forgiving and hides the chubbiest part of my arms, and the band that grips me lower on the arm gives the illusion of slenderness.
Also, dark colors. Any time I wear white or pastels, my arms automatically look bigger.
Also try short-sleeved batwing or dolman tops. Upper arms are completely hidden in these!
Lastly, I've found that sleeveless tops that show *more shoulder* give the illusion of smaller arms, so halter tops and
U-neck tops are a great option. HTH!
Cheers,
A thick-armed gal
