Swimsuit shopping for me is about as much fun as going to the dentist, so each rare time I find success I can't wait to share with you guys. My bust fluctuates from time to time with weight changes, and I prefer shaped, underwire cups that have good structure. It's tough to get the cups right - I own some where the band fits but the cups are soo itty bitty, or the cups are a little too curved/wide and nip slips keep Nick constantly on edge.
I know many of you also need small band sizes but have fuller busts, so I was especially excited that ASOS swimwear makes both extended band sizing and fuller bust cups! Their size ranges start in 30A - 30J going up to 42 in band size. Swimwear is often done in general letter sizing (s, m, l, etc) so it's helpful to have such specific numerical sizing for finding a good fit. Here's a few other options in a similar cut to mine:
I've had several questions about the coverage of ASOS bottoms, so this is what the "brief" cut looks like from the back. I would say it's medium coverage compared to other suits I've tried.
Here are all the suits ASOS makes in a style similar to Triangl's - they call it their contrast collection. You can mix and match regular bust strapless or fuller bust with halter strap, and bikini, high-waisted, or hipster bottoms.
