We have a lot of 3 vintage sweater clips. From top to bottom in the first photo they are as follow:
The top one measures about 7 1/2" with the clips measuring about 1 1/4". The clips are a confetti background with shells. I purchased this as a sweater clip but it I'm not so sure it was not handmade with the clips actually being clip earrings. The faux pearl chain is applied securely.
The center one I'm estimating it is from somewhere between the 1960's - 1980's. It is a gold tone metal with double chains, 1 linked faux pearls and the other linked chain. The ends have blue hearts surrounded by a gold decoration. It measures about 7" in length with the end clips measuring about 1 1/8" x 3/4". It is in nice condition with minimal wear showing.
The bottom one dates somewhere from between the 1950's - 1970's. It has light pink covers over the clips (1 1/8" x 7/8"). The full sweater clip measures about 7 3/8" in length. A few of the pearls have some wear and loss of finish on close inspection. I would still consider it in good condition with some vintage wear.
