ASOS swimwear / bikinis in extended band sizes (for both petite and full busts)

ASOS bikini in Japanese Floral

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. I have a small bust (my bra sizes range from 30A to 32A) that 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. And to make the good prices even better, all full priced items on ASOS are 20% off now with code LONGWKND (ends Tuesday; valid in US & Canada). Here's a few other options in a similar cut to mine:

Talbots sandals (4 colors, on sale! $50 after discounts), Mar Y Sol tote

Ray Ban aviators in blue/gold, old scarf (see how to tie as a coverup top)

The best way to navigate their big swimsuit selection is by filtering for your size on the left hand navigation panel. Oftentimes they will have separate listings for the same suit in regular bust sizes versus fuller bust sizes, and their tops and bottom pieces are usually listed separately so don't forget to add both pieces to your cart!I'm wearing the longline bikini in Japanese Floral in 32A and bottoms in US 0 / EUR 32. I first tried 30A in the top and it was too small both in the band and cups for me, but sizing up did the trick without leaving any gapping in the cups.

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.

My favorite is still Triangl's underwire bikinis (see my review) due to the material, structure, and better rounded shape of the cups. However I know their shipping policies are not convenient (plus several customers have been hit with custom fees), so wanted to share this as an alternative. Here's how the two suits look side-by-side.

You can see below that the coverage of ASOS and Triangl's bikini-style bottoms are pretty similar. Triangl is cut slightly wider at the top but narrower as you get down towards the crotch, whereas ASOS is the opposite.
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.
