This pattern has some interesting construction features, looking at the line drawing:
|MISSES' DRESS: Dress has low neckline slit, close-fitting bodice cut-in-one with sleeves (slit), side back bodice extending into uderarm gusset, lined midriff, single-layer tie ends (wrongside shows), skirt with side front/side back seams, side front pockets/vents, invisible back zipper, stitched hems, and self-bias binding. Topstitching and edgestitching.|
|FABRICS: Synthetic Suede, Lightweight Double Knit.|
|Unsuitable for obvious diagonals.|
From reading the description, it sounds like the bodice has some unconventional construction features, including a lack of side seams and underarm gussets (shades of retro-fifties dresses!).
I have never done an FBA on a dress made like this, so a muslin is definitely in order. Especially since I want one of these for myself..
(On a side note, do the pattern companies ever say This pattern suitable for obvious diagonals?I don't think I have ever seen that. Diagonal prints can be very flattering. I wonder why they hate them.
The pattern matching n this one would be a puzzle, so I think that's why they don't recommend it)
I'm watching for the next Vogue sale, because this pattern will be mine.
