Bumps up your outfit

Warm and fitted, no pockets. Still a little snug for my broad shoulders. But it makes whatever you're wearing look better.

Nice spring jacket

Thinner and slightly tighter in the sleeves but still a nice lightweight and lined jacket.

Maybe size up

First ordered in a size 10, needed to order a size 12. And then I loved it! I wore it a lot and received many compliments! Don't rent if you don't like shoulder pads. I should have rented it earlier than April in North Carolina because the jacket is pretty warm, and it's time to transition to something lighter here. Recommended!

Nice jacket for layering.

I wore this jacket over a dark green blouse and paired it with dark wide leg jeans and brown booties.

Perfect SF summer jacket

Loved this and am sad to see it go. Nicely shaped and warm - perfect for San Francisco on a foggy day when you want to look put together. This is a lousy photo, but it’s quite flattering. Will definitely rent again in August.

Good Basic Piece

It felt structured yet casual. I styled it a couple different ways, it was very versatile. I wore a size 4, and although it felt like a perfect fit, it would have been tight to button up. It was much warmer and itchier than I expected. I’ll probably use a couple times during my rental period but most likely won’t rent again.

The most perfect blazer/jacket!

If I had one piece of clothing that went with everything and could be dressed up or down, the ‘what to wear’ dilemma could be solved. This one piece of clothing does exactly that. I will own this jacket in the very near future. #sellinghousestobuyclothes

Absolutely love this blazer. I should have went up one size to accommodate for my bust area. However I can still wear it just can’t button it. Looks great with jeans for a more casual look but could stun with corporate work outfit also

Class up and brighten your winter blacks with this great warm cream-colored blazer. Has just enough tailoring and texture to be a departure from the ordinary. Wore twice!

I couldnt button this top except on the bottom button. It was also strangely wrinkled. I loved the style, but I shouldve gotten the size 4.

Fit was perfect with a long sleeve white tee underneath. Wore with slacks but would have been cute with jeans also. Jacket was warmer than I thought it would be which was great. Lots of compliments.

Almost bought this one.

It took everything in me to send this one back, but I finally decided that I needed to try all the options RTR offers before committing to the price of this jacket. It is such a great style, going with so many things--jeans, pants, skirts, and over dresses. I wore this jacket constantly. It is great for my petite frame--fit my shoulders and arms as if it were made for me.
