large arm circumference

theodora04 | Posted in Fitting on

I am making a muslin for a blouse and have discovered that my arm circumference is 2″ larger than the size I am cutting.  Do I slash the sleeve at the top and add the entire amount here?  or should I add at the top of the sleeve (1″) and at the bottom of the sleeve (1″ )  Would I then make the same corresponding changes to the blouse front and back?   I also have a broad back (which I made a slash and added fabric in the back for), but it also seems that I have hollow upper chest (above the bust) because the fabric is kind of bagging out above the bust?  Any suggestions?  The last blouse I made (different pattern) fit okay, but the arm feels small above and at the elbow, but the armhole itself fits well.  Thanks !

    You really need the newest issue of Threads. Two of your fitting problems are addressed there. It sounds like you may have to do the same alterations I do for myself. I frequently use a size l6 across the back for the extra room I need and a size l4 in the front. I usually ease the little extra at the shoulder seam but a little dart works also.

    hello, I have a similar sleeve problem and no dont addit in all the way through Its not a goodlook. I use the Palmer Pletsch book on fitting problems and it is exceelent. I dont have it with me right now so I I cant remember what to do but you will end up with an increase in only the upper arm circumference and not just a huge sleeve.You can get the book 2nd hand very cheaply from Amazon.A great investment.

      You can also add a center seam and use it to shape and add where you need the room.
