Part Deux of our Full Bust Adjustment festival, this tutorial will show you how to increase the size of an existing dart. I'll be using our Party Dress pattern (Kwik Sew #3521) as an example.
Most commercial patterns draft for a B cup, so many people have to alter up or down accordingly. On some patterns, you can fudge it a bit, or just get by - this is one of those patterns for me. It has always been a bit snug in the bust - but workable - now it's noticeably tight. My weight goes up and down a lot, and of course it all settles in the bust which means I have to alter almost everything I own. Hooray! Plenty of practice... Here's a picture where you can see that the existing dress squishes the bust a bit:
So, we'll be using the same slash-and-spread technique as we used previously in the Full Bust Adjustment aka FBA post along with the same supply list and cup size measurement chart. It might be a good idea to read through that post to refresh your memory - you can refer to it for all the step-by-step pictures I'll talk about below.
Here we go!
