Loving Ulla!

I've rented dresses before from Ulla, but really loved this top! The material was light. Paired it with cropped, cream jeans to head out for a birthday dinner.

LOVE - will rent again

Such a cute top for summer! Wore to the beach for a weekend get away and then again to work later that week. So cute and will probably rent again later this summer.

Obsessed

Colors are great. Sleeve is fun. I think it's a bit large for a 12. I will probably end up buying this to wear all summer

A little short

Top was a little short but worked well tucked in. Probably would size up to 4 next time.

A little too trapeze shape

Cute top. Easy with jeans. Love the quilted detail on the yoke. A little too full-too much of a trapeze shape for me. I have it a little half tuck and that helped

Great Summer Shirt

I've rented this top a few times, it's a great casual top for warm weather. It is cut generously but is still flattering and I would say true to size. Looks great with jeans or shorts.

Cute top - dress up or down

This is a super cute top - it has a bit of padding and structure to it which helps maintain the shape at the top - also could make it a little warm to wear. I wore this to work with shorts and really liked it - will wear again.
