Will gymshark sports bras eventually stretch out the more I wear them?

I bought two sports bras in different colors (boost bra, light support) both size Small. No issue with spillage but it's pretty tight around the ribcage (I prefer looser fits in general since I don't require much support). And even when I loosen the straps to max length, it cuts into my shoulder/neck fat more than I'd like lol.

Problem is, there are no more Mediums in stock. I've been checking for the last month and now my return window ends in a couple days. Does anyone have personal experience of a gymshark sports bra stretching out over time?
