I've read two pseudo-historical-fantasy-teen-romances recently: Marissa Doyle's Betwitching Season (Regency/Fantasy Wrede-Sternmer knockoff) and Anne Osterlund's Aurelia (psuedo-18th-century, fairy-tale, empowerment romance). They both have those fashionable photographic covers: pretty girl in a pretty, frilly dress.

This is a silly and petty thing to get annoyed about I know, but it's so obvious, even at a glance, that the lace is cheap machine-done stuff, and that the embroidery was machined onto the fabric on the bolt, with the dress-maker not bothering to make it match along the seams at all. The fan is most clearly plastic, and its ribbon trim isn't even pasted on evenly. The lace of the sleeve is not only the flat and cheap Barbie's-Bride-Costume variety, but it isn't even sewn on well. I bet I could photo-shop something better.
