I have become addicted to repairing and revamping my wardrobe! It's a really fun and resourceful way of feeling like you've got new clothes without spending loads of money. Here is a dress I picked up in one of Traid's brilliant £2 sales (these take place a few times a year) As you can see it's a nice pink gingham shirt dress but it's a bit of a boring, frumpy shape.
This is one of the techniques I share in my 'Introduction to garment alterations' and 'Refresh your Wardrobe' classes. How to adjust an over sized top or dress through the use of elasticated channels.
Decide where you'd like to adjust the garment. This shirt dress had a buttoned opening so it was easy to access the inside without having to unpick a side seam. Pin on a cotton tape, wide enough to accommodate elastic ( I used 1" wide ) Machine stitch on each outer edge, creating a channel. thread elastic through the channel, leave on the roll or as a length until you have pulled and gather to the desired reduction. Stitch the beginning and end of the elastic down inside the channel.
And there you go! A more flattering, fitted item! Adding multiple elasticated channels will give a ruched effect. Make sure you measure the space between each channel, so it looks nice and even. A subtle, easy way of reducing volume!
