Sweater sizing...

[ladyindica2000]

I have a pattern that I really really want to make. Its the cutest raglan sleeve, cowl neck sweater. The only problem? I keep second guessing myself on the sizing of the sweater. The smallest size of the sweater on the pattern has a 42" bust and 30" length. I have a 38" bust and am about 5'5". I normally wear about a size Medium and/or between an 8 and a 10. I keep thinking that the sweater will be big enough to fit me and have some room to it, but I am so paranoid that I will get finished and the sweater will be way to small or way too big (although bigger is better than too small). I have also measured a sweater of mine and the pattern seems large comapred to the sweater measurements, but I am still worried.

Also, the model shown is wearing a large and it only looks about 2 sizes too big (she has it sort of draped off her shoulder if that makes any sense).

So, hopefully someone can help me out. I have had the pattern and the yarn for about a month now and am too scared to try it out.

Thanks in advance!!
