It’s A Miracle Maternity
A wonderful young New York designer launches a line of trendy maternity
clothing. Wow! The tops have high necklines; many of the tops have
three-quarter-length sleeves; there are long-sleeved, crew-neck
maternity T-shirts; the sleeveless tops are great for layering; some of
the skirts are full length (I can’t tell if they have slits). And
she has evening wear too like lace and satin pants and a Jackie O Set.
