Georgia, can you tell us a bit about what your needs are in a cami? For example, for me, most camis have straps that are a little too long to provide good coverage, so I prefer adjustable straps. Also I like the length a bit longer.
More details would help, but I will tell you that I am enjoying the ones Angie recommends from Nordstrom's BP juniors collection. Very inexpensive and generous in length, but size up since they run small. The straps are not adjustable, but I have been able to deal with this since I like their other features.
