I'm afraid I even made a mistake the first time made. I looked at the shorter one when deciding on how much fabric. It worked out well in the end though. I bought some posh soft pink lining to go with the Liberty lawn and did around a 9 inch band round the bottom, then on the sleeves I did the same to catch up on fabric. It actually looked better with the plain contrast. Funny thing is the lining fabric piece never looks like it's not been ironed. The lawn looks okay but some bits could do with ironing out occasionally, especially the belt pieces.
This time I'm changing the side pockets and putting on the front. The fabric is so light that sometimes I had a job to find them. It's the way that the belt is done that I like best of all, no slipping and sliding so you finish up with more one end than the other and keep having to pull back.
