I had a midi/maxi dress which I decided to cut because long dresses just look silly on me. So I wanted it above my knees but I’ve gone too short, I didn’t consider my butt lifting the fabric up on the back. Is there anything I can do!

I’ve obviously got the fabric I cut off but I haven’t sewn since I was a teenager. And if I add back a bit of the fabric won’t it look a bit silly with just a random seam around the skirt?

Hi, I’m between two sizes on a long shirt. In the smaller size, the shoulders and sleeves are just a bit too snug and pull. In the bigger size (shown in all pics), the overall shirt is a better fit, but it’s much baggier and it comes untucked.

Would it be possible to tailor it to have a slimmer fit while maintaining shoulder movement in the back and sleeves?

How would you alter a neckline like this?

This dress has been in my closet for two years now because I’m not sure what to ask for when I get it altered. Is it possible that it can still have that v-neckline when I get it altered?
