Sizes Sold: 28DD-H, 30-40 AA-K, 42-54 A-N (US cup)
Shipping: US ($5 shipping, free with $70 purchase)
Bare Necessities offers a wide range of sizes to choose from. It carries more U.S. brands than many other sites, so be mindful of brands when looking for your size.

Beautyfull Bras
Main Brands: Curvy Kate, FitFully Yours, Parfait, Panache
Sizes Sold: A-K, 28-40
Shipping: US (shipping to US is 7% of order, international shipping fee is 20% of order)
Beautyfull bras is based in the US and has some very good prices (most bras in the $30-45 range), although brand selection is a bit limited.

Big Girls Bras
Main Brands: all brands listed here
Sizes Sold: Range includes 28-58 AA-N cup (mix of US and UK sizing), with not all bands available for all cup sizes (shop “by size” to see what’s available).

Brastop
Main Brands: Curvy Kate, Fantasie, Freya, Gossard, Krisline, Panache
Sizes Sold: 28-46 D-K
Shipping: UK (shipping to US: £6.95, or free with £75 purchase)
Brastop is one of my new favorite sites to order from. You can always find great deals and discounted prices on bras here – it’s a great choice if you need to order a variety of sizes to determine your size (you’ll have to pay for return shipping, however). Sometimes there will be codes for additional discounts or free shipping! Check back often for new selections and prices, just be aware that your size in any particular bra may get sold out if you wait too long.

Bravissimo
Main Brands: Bravissimo, Fantasie, Freya
Sizes Sold: 28-40 D-KK, 32L
Shipping: UK (shipping to US: £7.95)
Bravissimo is always chock-full of new offerings and beautiful bras in a wide range of sizes. It’s one of the easiest sites to use, in my opinion; you can search by size, style, brand, and color with the dropdown list, and it will update based on how many options are available depending on what you select. They will also offer very helpful fitting and sizing advice if you email them with questions.

Breakout Bras
Main Brands: Elomi, Fantasie, Freya, Panache
Sizes Sold: 28-38 D-K
Shipping: US (free standard shipping)
Breakout Bras has a great page on fitting advice, as well as a larger selection of maternity items. They do offer a variety of sizes and brands, but it’s a bit hard to shop by size (select a category first). Their FAQ also states that they will match prices.

Butterfly Collection
Main Brands: Several choices in each of these
Sizes Sold: 30-38 D-K, 28E-K
Shipping: Canada (free US shipping)
One of the few Canadian-based bra sites, Butterfly Collection offers a good variety of brands with several choices each. The sizing choices are solid, though a bit limited in comparison to larger sites. US and UK sizing equivalents and fit recommendations are listed for each bra.

Ewa Michalak
Main Brands: Ewa Michalak
Sizes Sold: Can vary; generally 30-46 A-K stocked. 24-28 bands (as well as larger cup sizes) can be custom ordered.

Click on the English flag on the top of the page for an English-language version of the site. I’ve heard great things about these bras, and the prices aren’t bad either! Just be sure to convert to USD 😉

Figleaves
Main Brands: Chantelle, Fantasie, Freya, Gossard, Just Peachy, Panache, Wacoal (see all brands offered)
Sizes Sold: 28-46 AA-JJ (the majority of sizes within this range, with a few additional offerings in larger backs)
Shipping: UK ($4.95 US shipping)
Figleaves offers one of the widest varieties in terms of brand and size. If you want to explore a wider variety of brands, or you want to order a variety of bra sizes within the 28C-DD cup range from the same site (most small band/small cup sites stop at B or C), this is a good option.

FreshPair
Main Brands: Wacoal, Chantelle, Panache, Calvin Klein, Le Mystere

The 28 band offerings of FreshPair are a little small, but they have a solid array of brands to choose from, as well as a great range of large-band sizes.

Large Cup Lingerie 
Main Brands: Freya, Fantasie, Parfait, Miss Mandalay
Sizes Sold: Varying; 28 D-H, 30-36 D-K, 38 D-J, 40DD-G

LCL has a small but solid range of bras, and the prices are definitely reasonable (some in the 15GBP range)! The site is very easy to navigate.

Linda’s
Main Brands: Anita, Chantelle, Fantasie, Freya, Panache (all brands listed here)
Sizes Sold: 28AA-J, 30-56 AA-N (all sizes listed here)

I haven’t had much experience with Linda’s Online, but I do know that I’m impressed with the sizes and variety offered, as well as the user-friendly site and good bra advice!

The Little Bra Company 
Main Brands: Little Bra Company
Sizes Sold: 28-38A, 28-36B, 28-34C
Shipping: US ($5, free with $100 purchase)
With a very specific and focused marked, this is a great place to look for smaller-busted women who fit into their size range. 🙂

LoveBras
Main Brands: Curvy Kate, Fantasie, Freya, Gossard, Krisline, Panache
Sizes Sold: 28-48 D-K (all sizes listed here)

The Lovebras site setup reminds me of Brastop – the prices seem to be similar too!

Lula Lu Petite
Main Brands: Eberjay, Lula Lu, The Little Bra Company
Sizes Sold: 30AA-B, 32-36AAA-B, 38AA-A
Shipping: US (Varies by zip code – approximately $6)
Lula Lu Petite is the place to go for women who need sub-A cups (and/or find the options on The Little Bra Company too large in the cup) – there’s even a few swimwear options!

Sophisticated Pair
Main Brands: Elomi, Fantasie, Freya, Panache, Wacoal
Sizes Sold: 28-42 D-KK
Shipping: US ($7, or free with $50 purchase)
A smaller, US based site, A Sophisticated Pair has a smaller selection of some of the most popular bras.
