Where to Buy G Cup Bras in the US and UK

Find fuller-bust retailers by checking their sizing systems, fitting services and complete-size options.

The useful answer

Start with a retailer or brand that lets you filter by both band and cup, then confirm whether the displayed G is UK or US. Specialist fuller-bust shops and brand-direct collections are two practical routes; compare the exact model, delivery region and returns before ordering.

For a UK G label, start with a specialist fuller-bust range that displays UK cup letters and the full band-and-cup combination. Bravissimo has a published G-cup category and US storefront; identify the country selector before using its filters. In the US, Wacoal America also has a published G-cup category. That page mixes Wacoal and related brands, so inspect the product’s own sizing system instead of assuming that every G shown means the same cup. These are examples of search routes confirmed on 25 September 2026, not endorsements or promises that a size is currently in stock.

A department-store filter can be useful if it declares its cup convention. Nordstrom publishes a US cup-size conversion guide; its US G corresponds to UK F in that guide. If your starting label is UK G, a US G filter can lead to a different cup position. Translate the full size before filtering, then inspect the garment label and retailer explanation.

Enter the band and cup together. A category called “G cup bras” can show models with different band ranges, converted storefront labels and colours with different stock. Open the specific model and colour, confirm its own size selector, then check the tag system. If the seller offers a fit note for that model, compare its construction with the bra you already wear rather than treating the category label as a fit guarantee.

Check the country of dispatch, whether return postage is prepaid, any import charges and the period for returning an unworn bra. Keep these details separate from the item price; a low listed price may not be the lowest cost if a first try-on fails. Enter only fees stated by the seller in the calculator below. Its return scenario assumes that only the item price is refunded, so adjust your inputs to the retailer’s actual policy.

The requested inputs are item price, outbound shipping, known taxes / import fees, return postage or fee. Keep the unit or chart context with the result. Blank inputs are not treated as zero, and unsupported values should be corrected rather than used to produce a convenient-looking answer.

Enter all amounts in one currency. The purchase estimate adds item price, delivery and the known fees you supply. The return scenario assumes the item price is refunded but the original shipping and entered fees are not, then adds the return charge. This is an explicit scenario rather than a statement about a particular retailer.

For example, an item costing 49, shipping of 6 and known fees of 5 costs 60 delivered. If returning the item costs another 4 and only 49 is refunded, the unrecovered cost is 15. If your retailer refunds delivery or a fee, change the assumptions before using that result for a decision.

Read the actual deadline and eligibility conditions before ordering multiple sizes. Swimwear, adhesive products and altered garments can have different conditions. A low purchase price may be less useful than clear size information, access to fitting help and a workable return destination. The tool does not calculate customs rules or live exchange rates.

Common questions

Where can I start looking for a UK G bra?
A fuller-bust specialist with UK size filters is a practical starting route. Bravissimo publishes a G-cup category. Verify your exact band, model, market and current availability before treating a listing as suitable.
Does a US G filter show a UK G?
Usually not on the chart used here: US G aligns with UK F, while UK G aligns with US I. Confirm the retailer’s displayed system and the garment label.
Can this page show current prices or stock?
No. The shopping examples identify places to check, and the calculator uses the price and fees you enter. Read the seller’s current listing and returns terms before ordering.
