I bought a cute, simple black dress online for a party only to discover it is too short (short enough that if a jump, a little too much shows)! I love the dress except for the shortness bit. I was thinking I could take it to a alteration/tailor place and have them sew black cloth made of the same material to the bottom but Im not sure. The party is in a week and I already bought matching accessories for the dress! What should I do???
