Great colors and blazer!

Would rent again! Nice heavy weight. The rushing in the arms is a little snug around the forearm, but otherwise no bc complaints.

Loved the style

Tight in the back so I was restricted if I needed to extend my arms otherwise it was vibrant and stunning. I sized up too but you must need a narrow back for this.

Pink Perfection

I wasn't in love with this, but dang - I haven't received that many compliments on a rental in a long time (including from my husband, who usually asks which circus act I'm taking part of as I'm on my way out the door). If you want to feel great about yourself, rent this jacket!

Obsessed! But size up!!

I sized up one and wish I’d gone two. I have broader shoulders and a larger chest.

it's good but not amazing

i will wear casually but it's nothing you'd be walking down the street in and people would stop you for. i will say, it's warm and that is a plus for me.

Cute, runs small

Very cute and well made, but runs a little small in chest and shoulders.

Love the colors. Not happy with the fit.

Definitely runs small. I sized up but it still felt too tight in the arms and waist.

It's thick and can add some bulk.

I wanted to love it, but just "ok"

Color and material are sooooo cute, but the fit is a little short and sleeves are scrunched up in an unflattering way. Ended up not wearing it.

Too tight

First, I want to say this blazer is beautiful! I wish it fit but it ran small. I usually wear a 2 in this designer and the 4 I ordered I couldn’t get over my shoulders. Just order 2 sizes up from your size

Ran a little small

I wanted to love this like I do most things from this designer, but found this to be a little tight in the back. Would rent again one size up! Great quality and heavy.

Runs small

Very wintry / heavy. Fit too small on the sleeves for me. Ended up sending back without wearing it as it just wasn’t comfortable.
