It's very subtle, but the necklace echos the print of the skirt, that's some ninja outfitting!
These rings are from Jewel Mint, but sold separately, and happily work really well together as a stacked set.
Just a simple little outfit for a fun Saturday afternoon stroll. Wearing all back in summer can be really chic, but I find that the accessories should be on the subtle, daintier side. You don't want to look too weighed down in the heat with chunky jewelry, or overly complicated shoes when doing all black, especially if it's a bit more covered up like this short-sleeved tee, as opposed to tank or strappy dress.
