Hello, and welcome,
How about wearing (large or medium) earrings instead of a necklace?
Are you sure you need a jacket? If so, how about a burgunder velvet blazer (for winter) or a white linen blazer (for summer)? I guess there are many more possibilities, depending on your age, personality, preferences, body shape, life style and the actual occasions where you want to wear the jumpsuit.
These suggestions are rather general, as I know very little about you. Please consider to put some info into your profile. This will help others to give you more specific advice, and is a nice and practical way to introduce yourself to this forum. (You might enjoy reading other forum members' profiles.
