I always struggle to find feminine women's clothes to fit my xxtall skinny build - but I have just discovered Patty Boutik. They have a range of tops which are really cute, and sleeve lengths which actually ARE full length! They have a few high neck items too, which are great for covering Adams apple, and makes you neck more slender. Just take care with size - I'm 38d and size 16 was a little large, but still fit OK, just that a 14 would have been more figure hugging!
