Like Lace?  Check Roaman's and BCO
Roamans.com has a few really pretty pieces right now with lots of lace.  short sleeved or no-sleeve dresses and tops are fairly easy to find, but they do have a few long sleeve items as well.
Mostly polyester.  
I found two long sleeved, 30" long tunics.  The "Juliet" "lace big shirt is really pretty in a salmon color they call "sweet melon", a shade of turquoise blue, a pinkish beige, and blue-navy,   I also like the "Emma" clip dot chiffon tunic.  I wish they had a longer length that would fit me the way this fits the model. 

BCO.com (the Redcats group discount outlet) has at least three 30" tunics.  
The first is a lace trim chiffon tunic from Roamans with an elbow length sleeve.  It comes in oatmeal and the pinkish beige they call "pretty taupe".  It's has lace sleeves and yoke for $29.99  
They also have a 30" long, 3/4 length sleeve top with lace inserts covering the shoulder and outer 5th of the sleeves.  This one is made of cotton/modal.  
For cotton/spandex, try the crinkle knit gauze ruffle tunic with eyelet.  It's from Roamans. but apparently BCO is handling the  outlet, clearing the final sizes.

These are only a few of the lace items in the catalog.
Just remember, at BCO, these are discount outlet prices and limited quantities.  It you're interested move fast, because they often go FAST.

Be beautiful!
