I used a pattern - Butterick 6534, as seen here: http://store.sewingtoday.com/cgi-bin/butterick/shop.cgi?s.item.B6534=x&TI=10003&page=5
I was lucky enough to get this pattern, plus another identical one in a children's size, in a clearance. Because there's several variations on shrugs and you are a beginner sewer I'd suggest you look closely at the pattern before you buy. The one I used was just one piece, so you didn't have the hassle of setting in sleeves (which can be tedious with flimsy and/or sheer fabrics). The Torrid one that you like has set in sleeves, which would mean in that see-through fabric you've got to get the armholes neat (not impossible - I've done it, but it can be frustrating for beginners). That was why I liked the Butterick pattern. My scanner has gone all wibbly on me, so here's the best I can do:
The advantage of just one piece was that I could use a patterned fabric (I was reconstructing from a thrift store wrap which had colours that I wanted) and adjust it to get good symmetry from the pattern, which can be trickier if you've got 3 pieces to put together. Here's a photo to show what I mean:
. I thought it was cool to get such a dramatic pattern lined up like this but it was much easier to do with a single pattern piece!
From the front:
The one you like has ties in front - they would be really, really easy to draft onto your pattern - just adjust the pattern piece to suit what you are adding or adjusting and this pattern is simple enough for you to get brave and just freehand it. If I ever have time to sew again (Uni work is killing me) I want to try versions with fringes, bell sleeves and perhaps something dramatic that kind of drapes down at the back like a bit of a cape or something. I might try these variations on the children's version so my daughter can enjoy the proceeds!
A note on the flimsy fabrics - your pattern will include pieces intended as a guide for making bias binding (something you do to flimsies to make neat edges). If you are a real novice or are pushed for time, just buy a package of bias binding - you can get matte or satin finishes and they save you bucketloads of time!
