For dressing up or dressing down...: Susanna is a fabulous women's clothing store. If you need an elegant evening gown, they have it. If you need a nice sweater to wear in the office, they have that too. And if you want a cute and unique top for bar-hopping, you can find it here. It's a boutique, but the prices are well rounded. And when you find that perfect outfit, rest assured that the accessory and jewelry selection is amazing. Also amazing are the wonderful and helpful (but never pushy) staff.

I had one week to go before my trip to England and nothing appropriate to wear.  My sister and I would be hiking and theatre going and we promised each other to "pack light."  I was becoming frantic.

I stopped in Susanna in Cambridge and they had everything I needed.  I'm not a great shopper so Amy took me by the hand and created several mix and match outfits that look fabulous.  I'm not thin but she even managed to make me look 10 lbs thinner!  

Susanna is not expensive compared to travel clothing lines like Travel Smith and you don't look like every other tourist.  I think this shop is extra special.  There is an atmosphere that is welcoming and helpful.  There are many, many choices and wonderful unique pieces that are beautiful and fun to wear, and aren't high maintenance.  Their jewelry is fabulous.  I bought a little black sparkle necklace with pull strings that will be easy to pack and add a little dressed up look to my wonderful tops.

In the days of indifferent and uninterested employees in the Mall and the impersonal, hit and miss with sizes, internet shopping experience I think that Susanna is a fabulous place to shop and everyone there is wonderful and they really care if you leave happy!  

I'm off to England on a long awaited trip with my sister and I will be looking pretty darn good thanks to Amy and the wonderful shop Susanna.
