Product details

Some pieces do the work of a shirt without ever asking to be tucked in.

Meet Foster, a long-sleeve polo sweater with an open polo collar and no buttons to fuss with. The fine-knit surface stays smooth rather than chunky, the cuffs sit close at the wrist, and the slim-fit shape follows the body instead of hanging off it.

Wear it to the office under a jacket, out to dinner on its own, or at the weekend with dark trousers.

Why You'll Love It

  • Open polo collar: the finish of a collared shirt with none of the stiffness.
  • Fine-knit surface: reads neat under a blazer and stays that way through the day.
  • Fitted cuffs: sleeves stay where you push them instead of sliding back down.
  • Pull-on shape: no buttons, no placket, nothing to line up in the mirror.
  • Navy: the colour that carries grey, camel and off-white without a second thought.

Size & fit: A slim fit that follows the chest and waist, so take the next size up if you want more room. Available in M to 4XL; the chart in Size & fit gives the maker's flat measurements in inches and centimetres.

Care: Machine wash below 30°C, reshape while damp and dry flat.

Shipping

Shipping is free on every order within the United States, with tracking and no minimum order value. We ship to United States addresses only. Processing takes 1–2 business days (Monday to Friday, excluding US holidays) and delivery takes 5–10 business days after that, so most orders arrive within 6–12 business days. Your order is packed and dispatched by our fulfillment partner. You receive a shipping confirmation email with a tracking link, and you can follow your parcel on our Track Your Order page. The rest is in our Shipping Policy.

Returns & Refunds

You have 30 days from the day your order is delivered to request a return. Items must come back unworn and unwashed, with the original tags attached and in the packaging they arrived in. Both faulty and non-faulty items can be returned, and we do not charge a restocking fee. Mail info@alleboutique.com with your order number to start; once the return is approved we reply with the return address and the steps. Return shipping is paid by you when you changed your mind or the fit was not right, and by us when an item arrives defective, damaged or incorrect. Exchanges are welcome: start a return and tell us which item or size you would like instead, and we send the replacement as soon as your original item is on its way back to us. Approved refunds go back to your original payment method within 7 days of that inspection. The rest is in our Returns and Refund Policy.

Questions? Answered.

What size should I order?

Open Size & fit next to the size selector for available measurements. Clothing charts say whether they show body or garment measurements; shoe options use US sizes. Missing source measurements are marked rather than estimated. For help, email info@alleboutique.com.

What does shipping cost and how long does it take?

Nothing. Shipping is free on every order within the United States, with tracking and no minimum order value. We ship to United States addresses only. Processing takes 1–2 business days (Monday to Friday, excluding US holidays) and delivery takes 5–10 business days after that, so most orders arrive within 6–12 business days. See our Shipping Policy.

Can I return or exchange it?

Yes. You have 30 days from the day your order is delivered to request a return. Items must come back unworn and unwashed, with the original tags attached and in the packaging they arrived in. Exchanges are welcome: start a return and tell us which item or size you would like instead, and we send the replacement as soon as your original item is on its way back to us. Email info@alleboutique.com with your order number to start. See our Returns and Refund Policy.

What is it made of and how do I care for it?

Where the maker publishes the fabric composition and a care label, both are on the product page, word for word. Where the maker does not publish them, we do not fill them in ourselves — email info@alleboutique.com and we will ask on your behalf before you order.
