The First Mid-Season Dresses You’ll Wear in September

Although the start of each season usually comes with many on-trend proposals, there are more basic garments that are always a safe bet. And one of them is the long-sleeve dress. The perfect piece to make the transition from summer to autumn.

Our suggestion is to opt for a mid-length cut design, which you can wear inside or outside the office. A current proposal that completely outshines the spaghetti-strap designs we have worn during the summer, with which you will create the best looks to start the new season.

If you prefer to add a trendy touch to this proposal, choose a dress in a special color like orange. The ruffles play a very important role in these trans-seasonal proposals, and their mission is to ensure that the look never feels boring.

There’s no better moment than the start of September to make the most of long-sleeve dresses in the way you like best. If you’re looking for a fully on-trend look, opt for a bohemian-style printed design.
