WHAT TO WEAR WHEN TRANSITIONING FROM SUMMER TO FALL 2023
I know, coming up with the right casual transitional outfit idea that would let you transition from summer to fall in style can be quite challenging.
It’s either not warm enough to wear clothes from your summer capsule wardrobe. Or not enough cold just yet to wear the clothes from the capsule wardrobe you built for fall.
Furthermore, your summer clothes might not be fashionable anymore. Indeed, there are quite some pieces that will go out of style come September 2023.
Well, if you managed to build a transitional capsule closet with summer clothes that are still in style for fall 2023 and with a few last seasons clothes that are coming back in fashion for fall 2023, then you have an easier job to do. You have all the clothes that can be worn when transitioning from summer to fall 2023.
The only thing you need to do is to put them together in a fashionable way.
Don’t worry; I can help you with that. Scroll down to see 22 fashionable casual summer to fall transitional outfits now – 22 the best casual September outfits and stunning casual September outfit ideas!

TRENDY CASUAL SUMMER TO FALL TRANSITIONAL OUTFITS WITH A DRESS
Here are some outfit ideas for all of you who want to transition your favourite summer dress into fall.
1 CUT-OUT DRESS WITH CARDIGAN AND POINTY FLATS
To transition your favourite summer cut-out dress into fall, style it with this season’s must-have layer – the cardigan. Yes, cardigans are very fashionable for fall winter 2023. Ps. Don’t forget to swap sandals for fashionable pointy flats.
2 ONE SIDE SHOULDER WRAP DRESS WITH A COLLEGE JACKET
A green one side shoulder dress is one of the most fashionable fall 2023 dresses. Hence you don’t need to bother what jacket and shoes you will wear with a green dress in early fall. You can even wear any jacket and any shoes from your capsule wardrobe.
However, you might want to wear pointy slingbacks and a college jacket – two of the key fall 2023 fashion trends.
Ps. If you like this look, but actually don’t have a green dress like this, nor feel like buying a one side shoulder dress for fall – get this green dress with long sleeves. It will be perfect for fall 2023 and spring 2023.
3 LITTLE RED DRESS WITH CUT-OUT ANKLE BOOTS
Finally, a little red dress with balloon sleeves – the most fashionable dress of fall 2023.

I advise you to put on cut-out Chloe Rylee boots (buy here) since these ankle boots are just perfect for fall. Besides, the cut-out trend will be quite strong this fall.
A pair of stylish sneakers is a good option, too.
