yahhhh i am not sure turtle necks in the sahara desert sounds very fun. haha. but seriously, thats where I am at. so annoying. It sucks because I know it is totally not appropriate for me to be showing my boob line like you said....
2 weeks ago, i went to ann taylor outlet in marysville (is there one in the outlets down south?), and they had a few tops that h "approved" of..they were short sleeved and high-enough neckline, for $20 each...maybe you can try there if you have time? there were like 7 colors and 5 prints, so if it works for you, you would have plenty in rotation.
omg. i have the same issue about high-cut-tops still = big line separating my bewbs. it's nearly impossible to cover up.
h likes winter time because then i wear more turtle necks...
W doesn't wear turtlenecks for this reason. Or those sweaters with big collars.
Which is a shame, because I like them, even on not-so-well-endowed ladies (though maybe since they're the only ones who usually wear them that's why???).
