HAVE IT. New Look 6557. World's best tea-length sundress (no kidding, made it 4 times already in different fabrics & bodices). Yardage (B, crisscross V-neck): 3 1/8 (45"), 2 1/2 (60"). Yardage (A, halter): 2 3/4 (45"), 2 3/8 (60"), plus 2yd 3/8".
This look is both casual and lady like at the same time. I have a black skirt that's very similar to this and nude pumps of course. That grey T is something I would have to acquire though :)
