Is it your intention to stack both bracelets on the same wrist? The JUC is slightly heavier than the LOVE so wearing both together may take a bit of getting used to.
Some members have mentioned they wear a sweatband when working out/cleaning/typing to protect the bracelet but for me personally, because I’ve worn my bracelet for quite some time, I’m used to it and leave it as is. I wear a 17 LOVE and mine is slightly loose (the 16 did fit but kept getting stuck on my wristbone and I had to keep adjusting it so I knew that wasn’t going to work for me). I haven’t had any issues with my arm going numb but there have been times when I’ve woken up in the morning and the screw motif is imprinted on my wrist/arm because I slept on the bracelet/it got stuck while I was asleep.
If your JUC is a 15, then your LOVE should be a 16 - it allows your bracelets to sit together nicely without too much overlapping. In my case, I have a 17 LOVE and a 17 JUC and they scratch each other a lot because my JUC is slightly bigger
You might find the same thing happens if you end up with both bracelets in the same size and stack them.
See how you go at the boutique on Thursday - if wearing the bracelet is going to cause you lots of stress/not suitable for your lifestyle, then now may not be the time to get it. Hopefully your husband can return it and you can buy something that is enjoyable. It’s okay to ask questions - the LOVE is not a cheap item so you need to be sure it’s going to bring you joy when wearing it (especially if it’s a gift from your husband)
I do think you should consider the LOVE cuff though - it’s removable! Or maybe the small LOVE?
