<3 thank you for your response Mrs.31
I have never thought of going to a tailor for resizing lolita clothes (maybe because the thought of having to cut an expensive and holy item was incomprehensible) but having a professional do it seems like the way to go. I've seen few tailor shop around my neighborhood before, but i'm not at all sure how reputable they may be.
I didn't know that an A-Line dress would flatter a small body type, but they are one of my favorite type of dress, so it works out perfectly! and i'll look into the high waisted corset skirts, i've seen them before but haven't tried them out yet.
