Simplicity 2852 Blouse Adaptation

It's hard to find patterns that are Jewishly modest, but I never give up.  Here is one which requires only a minor alteration, to the neckline, to make it perfectly modest.  It's the Simplicity's 2852 pattern.

If you prefer to wear with a shell underneath, then perhaps any of the styles will work, except that your shell must not be too tight fitting in the sleeves for the sleeveless styles, or be too contrasting in color with the garment.  I don't like layered clothes because in the summer, it gets too uncomfortable.  So I chose Style A, with a minor alteration to the neckline, by adding a mock neckband.  Style B (without a shell) has its sleeve too flair at the bottom to be considered modest as it reveals your elbow when you bend your arm.  

For style A, without an additional neckband, the neckline would be immodest as it's width would expose the part of your shoulder that's slopes down from the neck.  See the inset on the bottom left.  Some people might choose to tighten the neckline by making pleats around it, or adjust the neckline height at the pattern level, but my personal preference has always been a mock neckband.  Happy sewing!
