This would be a great dress for a professional job:
This is the Belted Crepe Shirtdress by Lafayette 148 New York. Price tag: $798.00. Details: finesse crepe with a matching belt, approximately 39 1/2" from shoulder to hem, spread collar with concealed button front, long sleeves with button cuffs, approximately 6-inch center back slit, sheath silhouette, hem hits around knees, side zipper, acetate/polyester, dry-clean. Model is 5'10".
This is probably one of my favorite versions of a shirtdress that I have seen in a while. It is dressy enough for the office and makes an easy office outfit. Red is a power color and every one should have a dress in that color. I really wish that I could see this particular dress up close as I have no idea how that concealed placket is finished. Actually, I have never seen this done before on a dress or shirt without a full placket. Maybe I need to visit the local mall to see if there is anything with this feature.
As far as the pattern, I have never seen a pattern like this. EVER. Does this mean our pattern companies are failing to produce patterns with great deals? Yes, I think so. So, here is my suggestion:
Use a shirt or shirtdress pattern that you have already fitted. I used the Classic Shirt pattern by Liesl & Co in September of 2023 to make a shirtdress of a similar style. Here are the posts - Part 1, Part 2, Part 3. The instructions that I followed were good.
If you want to figure out the detail of the concealed button front, here is a start. This is the tutorial that I plan to use to make the Classic Shirt have a concealed button front.
As for the fabric, I do not know what Finesse Crepe is. So, I would suggest using a crepe that is the highest quality/price that you are comfortable with. Hope you are inspired to create something beautiful.
Happy Stitching!
