I am pretty curvy and a little heavier than I would like to be right now and this suit fit perfectly and was comfortable all day for a client meeting and plane ride. Could work as separates too!

Great suit! I needed to look important for a conference so bought the Yiyan jacket, Horton pants (black) and Elizabeth turtleneck in a hurry. It all fit, right out of the box (thank you MM Chat) and it WORKED! I made lots of great contacts and felt like a million bucks. Sublime
I ordered the Palm Toile Jacquard version of this jacket. The fit is amazing. TTS. I think it fits better/more comfortable than my camel version of this jacket. This is a woven fabric, not printed. It is AMAZING. The jacket looks so sharp and unique. It is heavier than a normal jacket from MMLaFleur but that is due to the fabric. It's not a "winter" jacket, but it probably won't be my go-to in the middle of summer.
Love this jacket! The light texture and fancy button really make any outfit classy. The fit is great through the shoulders and a little looser through the body but still with a nice silhouette—very stylish. I coffee my sleeves for a more casual look between meetings and then uncuffed to polish. It quickly looks lived in, which I like a lot.
Classic and comfortable. Goes well with the skirt or pants
I love the fabric and overall shape. But because I ordered it online (I tried out size 0 in store), it still feels a bit tight (size 2). I wonder whether size 4 will fit better. I wish the store has better inventory...
This jacket is so versatile. I've worn it with jeans and with a dress and got lots of compliments on it both times. Everyone asks where I got it and I'm excited to tell them about my experience at M.M. LaFleur.
Great shape and material! High quality and worth the price. Button could use a little more reinforcement. It was loose on my first wear.
Shopping for this item in the Boston store was a wonderful experience. My stylist Genesis was very knowledgeable about the various fabrics, fits and sizings. I plan to shop in store with her again. She was fabulous!
This may be my favorite piece of 2026. The jacket is incredibly well made, stylish, and fun. I wore it today and received multiple compliments- it’s a head turner for sure!
Love this blazer - somehow it’s both understated and a statement piece all in one. Perfect pop of fun for the office or events.
I saw this in the show room and ended up getting it with the matching pants. It may not look like much online, but the fabric is amazing- it has great texture and drape.
Great jacket for the days you need to suit up for the office.
I love everything I have purchased from M.M. LaFleur. I haven't returned anything. I read all the reviews before purchasing and they tend to help with sizing as well. It is a simple prcess to ordering things as well. I have a regular email come through when new things arrive.
A little disappointed but, keeping it. I am afraid to exchange for the next size down, plus I don't like dealing with returns. Love the deep navy color and the over-all length. The sleeves are a bit too long and might need alterations. I dislike the button in the front, which is an easy fix. The exterior fabric of the blazer is nice and put together well, the style shape is decent enough with modest coverage but, the interior fabric seems inferior in quality, and in the way it was put together but, l can live with it! The product seems okay for the money.
I love the Design of the jacket, but it was a little wrinkly when it came so I took it to the dry cleaners and had it pressed; but still it doesn’t have a crisp look that I would’ve liked. I purchased size 4, which Usually fits me well. The Circumference of The sleeves seems a little bigger than they should be. And The upper sleeves are where I feel the fabric looks most wrinkly.
Well structured, great material --- would purchase again in a heartbeat
Love the fit of the jacket and have in other material. However, this material is cheap appearing and rough in person and looks like a moving blanket.
Lots of threads hanging from it and the bottom doesn’t hold its shape / looks stretched out. I expected better quality for the price.
Have bought 2 Yiyan blazers and have been very happy with them. So of course when I wanted a new winter suit, I went for this blazer and pants in the same fabric. TTS. Excellent fabric and construction. Will wear for years. The weight of this heritage tweed means I can wear this blazer all winter and into spring.
Beautful jacket fits like a dream. However this is NOT. Repeat NOT a true camle hair color. This is a coffee with cream colored/light brown suit with cool under tones. Not color true to the image. Which is SO SAD.
I am officially obsessed with this blazer. It is beautifully made, very flattering, and the weight and feel of the fabric is very well balanced: not so heavy that it is too much for summer but not so light that it isn’t warm enough for shoulder season or cold AC. Buying in all colors. This is now my go-to suit.
High quality fabric. Good fit. True to size.
So obsessed with this blazer. I was worried it would be too long because I am a very evenly-proportioned 5-3, but it is perfect. I have an athletic build and the cut and slight stretch are perfect. Just need to purchase in black to round out my collection.
Perfect blazer. Gorgeous cut comfortable and beautiful.
Perfect jacket! Great fabric!
Love it. Beautiful color and styling. Fabric quality is outstanding. The extra stretch at the seams is great and the sizing is spot on. I will be back for more colors!

Fits as expected. Love the material and looks sharp.
Perfect fit on my 5'6" 170lb frame. Updated design. It is the professional look I wanted. Will wear it with a tie blouse. No alterations needed! Love the material.
Great fit, great design
This is my favorite suiting piece from MM LaFleur. The cut and quality are great (although I'm glad I had a gift card because the pricing is significantly higher than even a couple years ago). It's hard to find dark navy and the color is great. My measurements are 36-30-44 and size 8 worked well (sometimes I have to size up to accomodate my hips then get the bust taken in but no tailoring needed here).
The blazer was terrific, great quality and silhouette. But I am returning it because I bought it as part of a suit and the matching pants were a heartbreaker. Size 20 fit perfectly in the waistline but the legs were comical circus tents. I felt humiliated.
I wish that I had bought this blazer sooner. It is spectacular quality and a beautiful addition to my wardrobe!
I actually bought this in Navy. I wanted the black, but the black versions had inconsistent fits across the shoulders. I do like the blazer; it has a nice, professional fit. I definitely recommend trying on if you live near a store.
The Parisian green is stunning, and the fit is flattering on a curvy person.
Parisian Green is fantastic Perfect fit, usually wear a size 6 in MML blazers and this fits true to size so you can wear over tops. I like the single button on this style so it’s sleek and not bulky. Purchased the Parisian Green and it is so pretty and surprisingly can be paired with many colors. So happy I made this investment.
The most comfortable blazer I just upgraded my suiting to these from MM and can't believe how comfortable I am in them. I usually size up in suit jackets because without stretch I get uncomfortable and squirmy (ADHD) and I feel so much better wearing the right size now! The stretch in these suits are such a relief. I'm 5'5" and got one Yiyan and one Yasmine in different colors -- I'm right between normal and petite sizing depending on the item, and like having the variety. With my longer Yiyan I wear skinnier cut pants, and straight/wide leg with my Yasmine.
Could be serious or playful. The pattern is just right- not too big or too small of a houndstooth. I also like the use of black and sand rather than black and white. Soft structure because of fabric but style really makes you look polished without being fussy
Love! Fits perfectly, no alterations needed. Material is crisp and lighter in weight than expected. I feel confident and ready to woo!
