Suz glad you are seemingly on the mend:) Do take care.
Now the dresses! I have skimmed responses but didn't want to be swayed:)
I really like them both, but for me they are tunics not dresses. My sense it that wearing with them with leggings would work better than tights. The opaque tights to my eye are just not 'opaque' enough. Its hard to explain but the more sheer effect of the tights, breaks the line of the look for me. My eye wants to see a long dark column in the case of the navy dress.
For at home dressing, I find leggings much more comfortable than tights.
I would definitely only keep one for the moment and see how it works for you. I love the idea but I would like to see you put it into practice before you invested any further.
