Thank you all so much!
I did the sit down and cross legs test as Angie and others suggested. As much as I love this dress, I have to say that it's a little bit too short even with tights and boots. I do plan to wear it to work (with tights,boots and cardis). Otherwise I won't get much use out of it at all.
But I really really want to make it work so I'm thinking of taking it to a tailor. I measured and it can add 1-1.5 inches to the length. I don't know why I said 1/2 inch before, sorry. Have any of you done dress alternation like this before- let out the hem? Will it ruin the dress or it's a perfect normal thing to do?
Thanks and Happy Halloween!!
