Bitches! How are we storing our sweaters this summer?

I have a problem with nice sweaters in that…i bought a lot of them this winter and now I need to store them. They were an investment so I of course want to take good care of them but I also live in nyc so need to store them in the most space saving way. Have any of you used vacuum seal storage bags for your knits through the spring/summer? And if so, did they come out okay when you unpacked them the following fall/winter? Any tips/tricks/insight very appreciated! No one I’d trust more when it comes to my sweater babies 💗
