Elevate your wardrobe with these chic and stunning long sleeve midi and knee length dresses

Long sleeve midi dresses and knee length dresses don’t have to be frumpy, dowdy or overly modest. I can’t stand articles about how to dress over a certain age. It has nothing about age and everything to do with how something makes you feel. I love cap or longer length sleeves for not having to worry about how my arms look in photos. I don’t always want to be that woman with her hand on her hip in photos! I also sometimes want more coverage e.g. at the time of the month or when I have post vacation bloat. But just because I want more coverage at times, doesn’t mean I don’t still want to feel sexy and stylish. Keep reading for the best dresses for all seasons for an elegant but alluring aesthetic so you can feel your most confident and comfortable.

As a fashion editor I get to spend hours a day searching through different sites for the best pieces to share with you. So I’ve rounded up the most elegant but sexy and stylish long sleeve midi dresses and knee length dresses for this edit.

How to find the most flattering midi dress for you

There’s no hard and fast rules when it comes to fashion and I’d never tell anyone what to wear as it’s so personal and different for everyone. I’m just here to make suggestions for the most flattering looks and to help you feel your best. Cliché as it is, the pageant girl in me wants you to feel “confidently beautiful”.

Long sleeve knee length dresses and midi’s of any length are flattering on my tall ladies but can be more difficult to pull of as a petite. So, if you’re petite and/or muscular like me, either short or long with my hems are the most flattering. When it comes to midi dresses, look for style that are cut just below your knee or below your calf, rather than stopping mid calf.

Best long sleeve midi dresses

Long sleeve midi dresses often get a bag rap and stereotyped, especially when a more mature woman asks for one. They often get suggested matronly styles they don’t want to wear and wouldn’t feel good about wearing. Just because we’ve reached a certain age doesn’t mean we suddenly want to stop feeling feminine and sexy. If anything, I want to feel more so!

I don’t know who needs to hear this but don’t let anyone tell you what you should or shouldn’t wear or settle for less. Ask for more! From resort wear to formal wear, it’s out there as these stunning and sophisticated styles prove. It can just be tricky to find, as a lot of big name stores let the side down. Which is why some of your favorite stores might be missing from the edit.

Yes, I was cheeky and threw in a few cap sleeve and off the shoulder midi dresses as well. As I feel like it’s often our upper arms we are more concerned about than the whole arm.

Everyone’s style and taste in fashion is different. Even what people consider sexy is different. For me, it’s how a style makes me feel, not how it looks on the hanger. So if I missed the mark for you, drop me a message on Instagram and let me know more specifically what you’re looking for and the price point so I can try to help you out.

How to style midi and knee length dresses | Styling tips

Long sleeve knee length dresses can be hard to pull off, especially if you’re petite, like I mentioned before. You’re probably going to want to wear some kind of a heel with these.

If it’s too hot for sleeves or you prefer a shorter or sleeveless style but want to cover up your arms. Don’t forget about cape dresses and accessories like a beautiful silk scarf, long gloves which always make an outfit look more sophisticated, or a blazer.
