I am the mother of the groom and the wedding is in the Northeast in May.  It will be held ouside in a park.  I'm contemplating  a tea length dress in a neutral or pastel color.  Maybe a pretty spring hat.  Maybe heels.  Most of the dresses in the bridal stores are floor length, chiffon and have jackets.  I'm looking for a bit more casual.  But should be "special" and pretty.  Any suggestions??  I live in Florida and have heard it may be still cool up north in the spring.  Thanks!!
